A developer suspects recent edits to a checkout flow have created a bug based on flowerrors being emailed. Given the emails and some inputs known to trigger the issue, whichtwo activities should the developer consider in their investigation?
A. Use the Org Browser tool in the IDE to download the flow XML and run a diff report B. Look at the previous flow versions and compare them with the current one C. Open the Flow, Select Debug, Provide the Inputs, Select Run D. Open the Flow and select Attach to Live Session, Provide the Session Id, Select Attach
Answer: B,C
Explanation: To investigate a suspected bug in a checkout flow, comparing previous
versions of the flow with the current one can help identify changes that might have
introduced the bug. Additionally, Salesforce provides debugging capabilities within the Flow
Builder, where a developer can select the debug option, provide input values known to
trigger the issue, and execute the flow to observe its behavior, aiding in pinpointing the
source of the problem.
Question # 2
Which two statements are accurate?
A. A Lightning Web Component cannot contain an Aura component B. A Lightning Web Component can contain an Aura component C. An Aura component can contain a Lightning Web Component which contains an Auracomponent D. An Aura component can contain a Lightning Web Component
Answer: B,D
Explanation: A Lightning Web Component can contain an Aura component, and an Aura
component can contain a Lightning Web Component. This interoperability allows for a
smoother transition from Aura to LWC and enables developers to utilize the strengths of
both frameworks. However, nesting a Lightning Web Component within an Aura
component which in turn contains a Lightning Web Component (Option C) is not a standard
practice. For more information, refer to the Salesforce documentation on using Aura and
Lightning Web Components together:Salesforce Aura and LWC Interoperability
Documentation.
Question # 3
How can a developer bring in a checkout flow step to another sequence order?
A. drag and drop checkout Screens in main checkout flow B. drag and drop subflows in main checkout flow C. Adjust next-state in previous subflow configuration D. Reorder step in checkoutSteps.xml
Answer: C
Explanation: In Salesforce B2B Commerce, to reorder a checkout flow step within a
sequence, a developer must adjust the 'next-state' attribute in the configuration of the
preceding subflow. This approach allows for dynamic control over the sequence of
checkout steps without needing to modify the structure of the main checkout flow itself. The
Salesforce B2B Commerce documentation outlines how checkout flows are constructed
and how subflows can be managed and resequenced through configuration adjustments,
providing a flexible and maintainable way to customize the checkout experience.
Question # 4
In what way can a developer's code subscribe to platform events?
A. Flows and Apex Triggers B. Flows C. Apex Triggers D. Process Builder, Apex Triggers and Flows
Answer: A
Explanation: In Salesforce, developers can subscribe to platform events using both Flows
and Apex Triggers. This allows for the execution of automated processes in response to
the events. Apex Triggers can be written to respond to event messages in the same way
they respond to DML events. Similarly, Flows can be configured to trigger upon the receipt
of a platform event. This functionality is documented in Salesforce's developer guides and
best practices, which emphasize the versatility and power of combining declarative and
programmatic approaches to respond to platform events.
Question # 5
What is one requirement to keep in mind when including additional JavaScript 1h files in aLightning Web Component?
A. The files must be ES6 modules and must have names that are unique within thecomponent's folder. B. Only five of the files can be used with an import statement C. All the files must be imported to a singleton.js file and the singleton.js file can be usedwith an import statement D. Only one of the files can be used with an import statement
Answer: A
Explanation:
When including additional JavaScript files in a Lightning Web Component, it is required that
these files are ECMAScript 6 (ES6) modules and have unique names within the
component's folder. This ensures proper module resolution and avoids namespace
conflicts. Salesforce LWC documentation provides guidelines on organizing component
resources, including JavaScript modules, to ensure they are correctly recognized and
utilized within the LWC framework.
Question # 6
What are two maintainable ways that Lightning Web Components can be made mobileready? 33m 215
A. Create a Lightning app page and add the component to the mobile navigation B. Import a third party JavaScript library C. Install the mobile extensions plug-in for VS Code D. Decorate templates with mobile-ready
Answer: A,D
Explanation:
To make Lightning Web Components mobile-ready, one maintainable approach is to create
a Lightning app page and then add the component to the mobile navigation. This ensures
that the component is accessible and optimized for mobile users within the Salesforce
mobile app. Another approach is to design the component's templates with responsiveness
in mind, using CSS and layout techniques that adapt to different screen sizes. Salesforce
documentation on mobile-ready development practices provides guidelines on creating
responsive designs and optimizing components for mobile use.
Question # 7
A developer has just deployed a new Lightning Web Component to an authorized org.What should the developer do next to use the new component on apage?
A. Go to "Deploy LWC" in Setup. B. Navigate 3 to the Page, Click on the "Custom Component Editor,’ Click "Publish" on thenew component in the list and adjust the positioning. C. Create a Metadata API (MDAPI) conversion file with the Command Line interface (CLI)then go to the page and adjust the positioning. D. Go to the page, edit it, and drag the new component onto the page.
Answer: D
Explanation: After deploying a new Lightning Web Component (LWC) to an org, the
typical next step to use the component on a page involves navigating to that page, entering
the edit mode (usually through App Builder or a similar interface), and then dragging the
new component from the components palette onto the desired location on the page. This
process is consistent with Salesforce's modular design approach, allowing for easy
integration and configuration of components within the Salesforce ecosystem.
Question # 8
The ccrz.cc_hk_UserInterface apex class, HTMLHead Include Begin and HTML HeadInclude End Cloudcraze Page Include sections allow additional content to be added to theHTML <head> tag. What are two reasons that is it preferred to use theccrz.cc_hk_UserInterface extension over the Cloudcraze Page Include sections? (2answers)
A. Salesforce apex:include is wrapped in <span> tags. B. HTML does not support <div> tags inside the <head> C. Salesforce apex:include is wrapped in tags. D. HTML does not support <span> tags inside the <head>
Answer: A,D
Explanation:
The ccrz.cc_hk_UserInterface apex class is preferred over the HTMLHead Include Begin
and HTML Head Include End Cloudcraze Page Include sections because Salesforce apex:include is wrapped in <span> tags, which are not valid inside the HTML <head> tag.
This can cause rendering issues or unexpected behavior in some browsers. The
ccrz.cc_hk_UserInterface extension allows adding content to the HTML <head> tag without
using apex:include.
Question # 9
What does the developer need to implement to override Shipping in Checkout? 38m 04s
A. sfdc_commerce.CartShippingCharges B. sfdc_commerce ShippingCharges C. sfdc_checkout.ShippingCharges D. sfdc_checkout.CartShippingCharges
Answer: D
Explanation: To override shipping charges during the checkout process, the developer
needs to implement a specific interface, likelysfdc_checkout.CartShippingCharges. This
interface would allow for custom logic to calculate and apply shipping charges based on the
cart's contents and other criteria, ensuring flexibility and accuracy in handling shipping
costs within the checkout flow.
Question # 10
A developer needs to debug a flow tracing a single input in complete detail, watching allvariable changes as the checkout process is executed. Which feature should the developerenable? ~.
A. Show the details of what's executed and render flow in Lightning Experience B. Show the details of what's executed and render flow in Lightning Runtime C. Add watch to variables D. Show execution details inline
Answer: D
Explanation: To debug a flow with detailed tracing of a single input, including watching all
variable changes as the checkout process is executed, the developer should enable "Show
execution details" (inline) within the Flow Debugger. This feature allows developers to see
a step-by-step execution of the flow, including the values of variables at each step. This is
crucial for understanding how data is being passed through the flow and for identifying any
issues. Salesforce documentation on debugging flows provides more information on this
feature:Salesforce Flow Debugging Documentation.
Question # 11
How can a developer make an integration available for selection?
A. Modify the StoreIntegrated Service to map to an Apex class id usingworkbench B. Enter the integration class name and version in Store Administration C. Create a RegisteredExternalService record using Workbench D. The integration is available once it is uploaded
Answer: C
Explanation: To make an integration available for selection in Salesforce B2B Commerce,
a developer must create aRegisteredExternalServicerecord. This can be accomplished
using tools like Workbench, which allow for direct interaction with Salesforce's backend
database. By registering the external service, the integration becomes selectable within the
B2B Commerce setup, allowing it to be associated with specific stores or contexts.
Salesforce documentation on integrating external services with B2BCommerce provides
step-by-step instructions on registering these services to enable seamless integration and
functionality within the platform.
Question # 12
A developer is writing custom code to compare External Prices and Sales Prices for cartitems. What should be returned if the External Prices are the same as Sales Prices forProducts in the Cart? ~.
A. sfdc_checkout.IntegrationStatus.Status.SUCCESS B. sfdc_checkout.IntegrationStatus.Status.SUCCEEDED C. sfdc_checkout.IntegrationStatus.Status.ERROR D. sfdc_checkout.IntegrationStatus.Success.FAILED
Answer: A
Explanation: Similar to question 198, when custom code compares external prices with
sales prices for cart items and finds them to be the same, the appropriate return value
should indicate a successful comparison (such as
sfdc_checkout.IntegrationStatus.Status.SUCCESS). This signifies that the external
prices are aligned with the sales prices, and there are no conflicts.
Question # 13
What happens to all previous tax entries during tax implementation?
A. Modified with the new Tax calculation B. They are deleted from the Cart C. Saved prior to recalculation D. Ignored with the recalculation
Answer: C
Explanation: In general best practices for tax implementation in systems like Salesforce
B2B Commerce, previous tax entries are usually preserved or saved before any
recalculation is performed. This ensures that there is a record of the original tax
calculations before any modifications, which can be crucial for auditing, historical data
integrity, and in case the new tax calculation needs to be rolled back for any reason.
Question # 14
Which technique is used by Lightning Web Components to provide areas of swappable,customizable content?
A. <slot> elements B. JQuery templates C. MutationObservers D. CSS classes
Answer: A
Explanation: Lightning Web Components (LWC) use<slot>elements to define areas within
the component's template where content can be inserted dynamically. This feature, part of
the Web Components standard, allows for the creation of customizable and reusable
components. Salesforce developer documentation on LWC outlines the use of slots to build
flexible component interfaces, enabling developers to design components that can adapt to
various content structures and layouts.
Question # 15
Which wire adapter can a developer use to retrieve metadata about a specific object?
A. getObject B. getObjectMetadata C. All of the above D. getObjectinfo
Answer: D
Explanation: To retrieve metadata about a specific object in a Lightning Web Component,
a developer can use thegetObjectInfowire adapter. This adapter provides access to the
metadata of a specified Salesforce object, including fields, record types, and layouts, which
is essential for dynamic component rendering based on the object's schema.
Question # 16
A developer is attempting to write a Lightning Web component from scratch by first creatingthe HTML markup and receives an error. Which three tags when used as the first elementin the file would produce an error?
A. <template> B. <article> C. <body> D. <html>
Answer: B,C,D
Explanation: In a Lightning Web Component's HTML file, using<article>,<body>, or
<html>as the first (root) element would produce an error because the LWC framework
requires<template>as the root tag. The<template>tag is necessary for defining the
component's structure and supports the framework's reactive and rendering capabilities.
The use of other HTML tags as the root element is not supported and will result in an error
during component compilation or runtime. Refer to the Salesforce LWC documentation for
Which tool is used to retrieve and manipulate Salesforce data in a Lightning WebComponent?
A. Aura requests B. Wire adapters C. Proxy adapters D. XHR requests
Answer: B
Explanation: In Lightning Web Components, wire adapters are used to retrieve and
manipulate Salesforce data. Wire adapters abstract the underlying data access
mechanism, providing a declarative way to access Salesforce data and metadata.
Salesforce documentation on LWC and the@wiredecorator details how wire adapters can
be used to connect components to Salesforce data sources, including standard and custom
objects, facilitating reactive data binding and efficient data retrieval.
Question # 18
In which two ways can events fired from Lightning web components be handled?
A. Programmatically adding event listeners B. Adding callbacks to components C. Listening for all possible events at the document root D. Attaching handlers to DOM elements
Answer: A,D
Explanation: Two ways that events fired from Lightning web components can be handled
are programmatically adding event listeners and attaching handlers to DOM elements.
Programmatically adding event listeners is a way of handling events by using JavaScript
code to register functions that are invoked when an event occurs. The developer can use
methods such as addEventListener or @wire to add event listeners to components or
services that fire events. Attaching handlers to DOM elements is a way of handling events
by using HTML attributes to bind functions that are invoked when an event occurs. The
developer can use attributes such as onclick or onchange to attach handlers to DOM
elements that fire events. Adding callbacks to components is not a valid way of handling
events fired from Lightning web components, as it is not related to event handling, but
rather to asynchronous programming. Listening for all possible events at the document root
is not a valid way either, as it is not efficient or recommended for event handling, as it can
cause performance issues or conflicts with other event listeners. Salesforce References:
[Lightning WebComponents Developer Guide: Handle Events], [Lightning Web
Components Developer Guide: Communicate with Events]
Question # 19
A developer suspects that a defect exists in 30 lines of Apex code. How can the developeradd debug statements, run the block of apex code in isolation and observe the immediateresults?
A. Click the Check Out button in the storefront B. Use the Execute Anonymous window C. Activate Chrome dev tools and click the Check Out button in the Storefront D. Use the Execute Immediate window
Answer: B
Explanation: To debug a specific block of Apex code, the Execute Anonymous window in
the Salesforce Developer Console or an Integrated Development Environment (IDE) like
Visual Studio Code with the Salesforce Extension Pack can be used. This tool allows
developers to run Apex code snippets in isolation and observe the results immediately,
which is valuable for identifying and resolving defects within specific code blocks.
Question # 20
A developer is implementing an Inventory class for checkout. All the error states have beenhandled and now the developer needs to take the next step to indicate that inventory isavailable for all of the items and amounts in the cart. What should the next step be?
A. Return TRUE B. Return sfde_checkout.InventoryStatus. SUCCESS C. Return sfdc_checkout.IntegrationStatus. Status. SUCCESS D. Return sfdc_checkout.InventoryStatus.Status. SUCCESS
Answer: D
Explanation: When implementing an Inventory class for checkout and indicating that
inventory is available for all items and amounts in the cart, the correct step is to return
sfdc_checkout.InventoryStatus.Status.SUCCESS. This indicates to the checkout
process that the inventory check has passed and the items are available. Salesforce
documentation on customizing inventory validation in the checkout process would detail the
expected return types and values, ensuring that developers implement the inventory
checks in a manner consistent with the platform's requirements.
Question # 21
What tool can a developer use to investigate errors during development? 07m 42s
A. Streaming API Subscription Channel for Commerce Diagnostics Event Logging B. Commerce Diagnostics Event Logging JavaScript Console C. Lightning Web Component for Commerce Diagnostics Event Logging D. Custom Log Levels
Answer: A
Explanation: For investigating errors during development, Salesforce recommends using
the Streaming API Subscription Channel for Commerce Diagnostics Event Logging. This
tool allows developers to subscribe to a real-time feed of system events, including errors,
which can be crucial for diagnosing and resolving issues during development. The
Streaming API provides a robust mechanism for monitoring and debugging by delivering
secure, scalable, and customizable event notifications within Salesforce or through external
systems. This is outlined in Salesforce documentation related to the Streaming API and its
application in commerce diagnostics and event logging.
Question # 22
Which three files comprise the essential pieces of a Lightning Web Component that isnamed myComponent?
A. myComponent.html B. myNewComponent.css C. myComponent.js-meta.xml D. myComponent.aura E. myComponent.js
Answer: A,C,E
Explanation: A Lightning Web Component (LWC) consists of a minimum of three core
files: the template file (.html), the JavaScript file (.js), and the metadata configuration file
(.js-meta.xml). These files are essential for defining the structure, functionality, and
configuration of the component. For more information, review the Salesforce LWC
documentation:Salesforce LWC Documentation.
Question # 23
Which two items are required for a developer to bring picklist values into a Lightning WebComponent?
A. import { getPicklistvValues } from 'lightning/uiObjectinfoApi'; B. import { LightningElement, wire } from ‘lwc’; C. import { wire } from ‘lwc’; D. import { picklistValues } from 'lightning/uiObjectinfoApi’;
Answer: A,B
Explanation: To bring picklist values into a Lightning Web Component (LWC), a developer
needs to import specific modules from thelwcandlightning/uiObjectInfoApinamespaces.
ThegetPicklistValuesfunction from thelightning/uiObjectInfoApimodule is used to fetch the picklist values based on record type and field metadata. Additionally, importing{
LightningElement, wire }fromlwcis essential for defining the LWC class and using the
@wiredecorator to wire thegetPicklistValuesto a property orfunction. Salesforce
documentation on LWC and utilizing theuiObjectInfoApiprovides clear guidelines on how
to implement this functionality.
Question # 24
Universal Containers (UC) needs to display data from standard objects (entities) in a different format than whatcomes with B2B Commerce out of the box. In doing this, what is one advantage of usingthe Lightning DataService vs using a custom Controller class?
A. Lightning Data Service translates the developer's component implementation to aVisualForce page for backward compatibility. B. JavaScript proxies for transport objects are created in the developer's IDE automatically. C. The developer can read, create, or modify single records or metadata without writingApex code. D. There is a Visual Studio add-in that accelerates the layout process
Answer: C
Explanation: Lightning Data Service (LDS) is a Salesforce UI API layer that empowers
developers to perform CRUD operations and manage Salesforce data without the need for
custom Apex controllers. LDS is designed to improve performance, user interface
consistency, and developer productivity by handling data operations and sharing rules, thus
reducing the need for server-side code. For more details, refer to the Salesforce
documentation on Lightning Data Service:Salesforce Lightning Data Service
Documentation.
Question # 25
Which three considerations should a developer keep in mind when creating a tax provider?
A. What events to fire in the Lightning Web Component B. Whether to use JSON or XML C. Success criteria D. Whether an AppExchange package already exists E. How to handle errors
Answer: B,C,E
Explanation: When creating a tax provider in Salesforce B2B Commerce, developers
should consider the data format (JSON or XML) for interoperability with the tax service,
define clear success criteria to ensure accurate tax calculations, and implement robust
error handling to manage exceptions and failures gracefully. Salesforce B2B Commerce
documentation emphasizes the importance of these considerations for integrating external
services, ensuring reliability and consistency in tax calculations across different
jurisdictions and scenarios.
Question # 26
Which three file extensions are allowed in a Lightning Web Component folder?
A. .js-meta.xml B. .html C. .Js D. .gif E. .jar
Answer: A,B,C
Explanation: In a Lightning Web Component folder, the allowed file extensions include.jsmeta.
xmlfor the component's metadata,.htmlfor the component's markup, and.jsfor the
component's JavaScript class. These files are essential for defining the structure, behavior,
and metadata of a LWC. Salesforce LWC documentation provides detailed information on
the structure of a LWC bundle and the purpose of each file type within it.
Question # 27
Which two practices are allowed when it comes to naming a Lightning Web Componentsfolder and associated files?
A. Beginning with a lowercase letter B. Including whitespace C. Using a single hyphen (dash) D. Using a single underscore
Answer: A,C
Explanation: When naming a Lightning Web Components folder and associated files,
Salesforce best practices allow the name to begin with a lowercase letter and to use a
single hyphen (dash) for compound names.Whitespace and underscores are not
recommended in the naming convention. This is in line with web standards for custom
elements. More details can be found in the Salesforce LWC documentation on naming
conventions:Salesforce LWC Naming Conventions.
Question # 28
What should a developer's implementation code return if the External Prices are the sameas Sales Prices for Products in the Cart?
A. sfde_checkout.IntegrationStatus. Status. SUCCESS B. sfdc_checkout.IntegrationStatus. FAILED. Status C. sfdc_checkout.IntegrationStatus.Status.FAILED D. sfdc_checkout.IntegrationStatus.Success. STATUS
Answer: A
Explanation: When implementing code for external pricing comparisons, if the external
prices are the same as the sales prices for products in the cart, the implementation should
ideally return a status indicating success (such as
sfdc_checkout.IntegrationStatus.Status.SUCCESS). This indicates that the external
pricing verification has passed and there are no discrepancies between the external and
sales prices.
Question # 29
Which HTML element can be used as a root tag for a Lightning Web Component's HTMLfile?
A. <body> B. <article> C. <html> D. <template>
Answer: D
Explanation: In Lightning Web Components (LWC), the root tag for the component's
HTML file must be<template>. This tag defines the markup structure for the component
and is essential for the LWC framework to correctly render the component in the Salesforce Lightning Experience. The<template>tag is unique to LWC and is not interchangeable with
standard HTML tags like<body>,<article>, or<html>. For more information, see the
Salesforce LWC documentation:Salesforce LWC HTML Templates Documentation.
Question # 30
What target does a developer need to set in the js-meta.xml file when creating a customLWC component for use in the Checkout Flow?
A. lightning_FlowScreen B. lightning__CheckoutFlow C. Iwe__FlowComponent D. lwe__flow
Answer: C
Explanation: When creating a custom Lightning Web Component (LWC) for use in the
Checkout Flow, a developer must set the target in the js-meta.xml file to
lwc__FlowComponent. This target specifies that the LWC is intended for use within the
flow component framework, allowing it to be utilized specifically in the context of Salesforce
Flows, including those used in the checkout process. Salesforce documentation on
developing custom LWCs for various targets would detail this requirement, ensuring that
developers understand how to correctly package and deploy their components for the
intended use case.
Question # 31
A developer used slots to pass content from one Lightning Web Component to another.How can they access the.DOM for what was passed to those slots?
A. Call this.template.querySelector() and this.template.querySelectorAll() B. Call this.querySelector() passing an id C. Call this.querySelector() and this.querySelectorAll() D. Call this.template.querySelector() passing an id
Answer: A
Explanation: In Lightning Web Components, to access the DOM elements within the
component's template, including those passed into slots, developers use
this.template.querySelector()andthis.template.querySelectorAll(). These methods allow for querying the component's local DOM. Direct DOM manipulation or querying
outside the component's template is discouraged to maintain component encapsulation
and security. For more information, see the Salesforce LWC documentation on accessing
the DOM:Salesforce LWC DOM Access Documentation.
Question # 32
Which three files are required for a deployable Lightning Web Component calleddisplayMyData that will fetch and display data?
A. displayMyData.css B. displayMyData.js-meta.xml C. displayMyData.js D. displayMyDataController.cls E. displayMyData.html
Answer: A,B,E
Explanation: For a deployable Lightning Web Component likedisplayMyData, the
required files include the component's CSS file (displayMyData.css) for styling, the
metadata configuration file (displayMyData.js-meta.xml) for defining the component's
configuration and properties, and the template file (displayMyData.html) for the
component's HTML structure. The JavaScript file (displayMyData.js) contains the business
logic but is not listed as an option here. For deployment, these files are essential. Refer to the Salesforce LWC documentation for deployment requirements:Salesforce LWC
Deployment Documentation.
Question # 33
What are two common and maintainable ways the content layout of a Lightning WebComponent can be implemented?
A. Spreading layout styles across several separate components B. Styling the :host pseudo-element (or other elements) via the CSS file C. Using inline styles D. Applying SLDS classes to internal elements
Answer: B,D
Explanation: For maintainable and scalable Lightning Web Component development, it's
recommended to style components by targeting the :host pseudo-element in the
component's CSS file and by applying Salesforce Lightning Design System (SLDS) classes
to internal elements. These practices ensure consistent styling that aligns with Salesforce's
design standards and provides a clear separation of concerns between component
structure and styling.
Question # 34
Which interface does a developer have to implement to override Inventory in Checkout?
A. sfdc_commerce.ValidationCartinventory B. sfdc_commerce.CartinventoryValidation C. sfdc_checkout.InventoryCartVvalidation D. sfdc_checkout.CartinventoryValidation
Answer: D
Explanation: To override inventory in the checkout process, a developer must implement
thesfdc_checkout.CartinventoryValidationinterface. This interface provides the
necessary methods for custom inventory validation logic, allowing developers to define how
inventory checks are conducted during the checkout process. Salesforce documentation on
extending and customizing the checkout functionality in B2B Commerce would include
guidance on implementing this interface to meet specific inventory validation requirements.
Question # 35
Which three statements are accurate?
A. An Aura component can contain another Aura component B. An Aura component can contain a Lightning Web Component C. A Lightning Web Component can contain an Aura component D. A Lightning Web Component cannot contain an Aura component
Answer: A,B,D
Explanation: Salesforce documentation clarifies the interoperability between Aura and
Lightning Web Components (LWCs). An Aura component can indeed contain another Aura
component, as well as a LWC, allowing for a mix of component technologies in a single
application. However, due to the architectural and design principles of LWCs, a LWC
cannot contain an Aura component. This is because LWCs are designed to be lightweight
and leverage web standards, which makes them not fully compatible with the older Aura
component framework in terms of containment.
Question # 36
What are three standard page reference types?
A. standard__app B. standard__component C. standard__pageNamed D. comm_loginPage E. standard__recordDetailPage
Answer: A,B,E
Explanation: In Salesforce, standard page reference types are used within the Lightning
Component framework to reference different types of resources. The types include
standard__appfor Salesforce apps,standard__componentfor Lightning components, and
standard__recordPageto reference a specific record detail or edit page (not
standard__recordDetailPage, but it's implied). Thestandard__pageNamedand more details, refer to the Salesforce documentation on PageReference Types:Salesforce
PageReference Types Documentation.
Question # 37
A developer needs to bulk export all of the Product data from an org and does not haveaccess to Data Loader or Workbench. However, the Command Line Interface (CLI) isavailable. Which command allows the developer to accomplish this task?
A. sfdx force:data:treeiexport -q <path to file containing soql query> -x export-demo -d /tmp/sfdx-out -p B. sfdx force:data:tree:export -Product2 -all C. sfdx force:data:tree:export -o Product? D. sfdxforce:data:tree:export -h
Answer: A
Explanation: The Salesforce CLI command sfdx force:data:tree:export is used to export
data from an org into one or more JSON files1. The -q flag is used to specify the path to a
file containing a SOQL query, -x is used to specify the name of the exported file, -d is used
to specify the directory where the exported file will be saved, and -p is used to indicate that
all records returned by the SOQL query should be exported12. This command allows
developers to bulk export data from an org without needing access to Data Loader or
Workbench12. Therefore, option A is the correct answer. Please note that the actual SOQL
query and the directory path would need to be replaced with the appropriate values for the
specific use case.
Question # 38
Which three are considered code units, or discrete units of work within a transaction in thedebug logs?
A. Validation rule B. Apex class C. Web service invocation D. Lightning component load E. Workflow invocations
Answer: B,C,E
Explanation: In the context of Salesforce debug logs, code units represent discrete units

Question # 39
Which of these is a key pattern leveraged when building Lightning Web Components? 39m36s
A. Composition B. Inventory C. Juggling D. Normalization
Answer: A
Explanation: Composition is a key pattern in building Lightning Web Components (LWCs).
This approach involves creating small, reusable components that can be assembled to
form more complex interfaces. This pattern promotes modularity, reusability, and
maintainability in the development of web components, aligning with web standards and
best practices.
Question # 40
What class must a developer implement to override Pricing during the checkout?
A. sfdc_commerce.CartPriceCalculations B. sfdc_commerce.PriceCalculations C. sfdc_checkout.PriceCalculations D. sfdc_checkout.CartPriceCalculations
Answer: D
Explanation: To override pricing during the checkout process in Salesforce B2B
Commerce, a developer must implement a class specifically designed for this purpose,
such assfdc_checkout.CartPriceCalculations. This class would provide the necessary
framework for custom pricing logic to be applied during checkout, ensuring that any custom
pricing requirements are met.
Question # 41
Which component can be used in other Salesforce Experience templates outside of B2BCommerce?
A. Quick Order B. CMS Collection C. Product Detail Data D. Results Layout
Answer: B
Explanation: In Salesforce Experience Cloud, components like CMS Collection and
Results Layout are designed to be reusable across different Experience templates, not just
limited to B2B Commerce. CMS Collection allows for the display of CMS content in a
flexible and dynamic layout, while Results Layout can be used to present search or query
results in a customizable format. Salesforce documentation on Experience Cloud
components emphasizes the reusability and adaptability of these components across
various templates and contexts.
Question # 42
Which two user permissions in addition to View Setup and Configuration are required to bulk create Product data translations via Data Loader?
A. Import Custom Objects B. B2B Commerce Super User C. Create and set up Experiences D. Manage Translations
Answer: A,D
Explanation: To bulk create product data translations via Data Loader, permissions
beyond View Setup and Configuration are necessary. "Import Custom Objects" permission
is required to import bulk data into Salesforce, including translations for custom objects.
"Manage Translations" permission is essential for managing translation workbench settings
and importing/exporting translation files, which is crucial for handling product data
translations.
Question # 43
Which three decorators can be used in Lightning Web Components?
A. @api B. @track C. @wire D. @class E. @import
Answer: A,B,C
Explanation: In Lightning Web Components, the decorators@api,@track, and@wireplay
crucial roles. The@apidecorator is used to expose public properties and methods, making
them accessible to other components. The@trackdecorator is used to mark private
properties as reactive, so the UI updates when their values change. The@wiredecorator is
used to wire Apex methods or Salesforce data to the component. Salesforce
documentation on LWC development extensively covers these decorators, explaining their
usage and best practices.
Question # 44
In checkout, what event should the developer's code listen for in order to help troubleshootand respond to actions?
A. CommerceBubbleEvents B. CommerceErrorEvents C. CommerceActionEvents D. CommerceDiagnosticEvents
Answer: D
Explanation: To help troubleshoot and respond to actions in checkout, the developer’s
code should listen for CommerceDiagnosticEvents. CommerceDiagnosticEvents is an
event that is fired by Salesforce B2B Commerce when an error occurs in the storefront.
CommerceDiagnosticEvents contains information about the error, such as error code, error
message, error type, and error details. CommerceDiagnosticEvents can be subscribed by
other components or services that want to handle or display the error information in
different ways. The developer’s code can listen for CommerceDiagnosticEvents using
an aura:handler tag in Aura Components or an @wire decorator in Lightning web components. The developer’s code can also use the event information to perform custom
logic or actions based on the error, such as logging, reporting, or notifying.
CommerceBubbleEvents is not an event that the developer’s code should listen for in
checkout, as it is not related to troubleshooting or responding to actions.
CommerceBubbleEvents is an event that is fired by Salesforce B2B Commerce when a
user interacts with a bubble component in the storefront. A bubble component is a user
interface element that displays information or options in a pop-up window when clicked or
hovered over. CommerceBubbleEvents contains information about the user interaction,
such as bubble name, bubble type, and bubble value. CommerceErrorEvents is not an
event that the developer’s code should listen for in checkout either, as it is not related to
troubleshooting or responding to actions. CommerceErrorEvents is an event that is fired by
Salesforce B2B Commerce when a validation error occurs in the storefront.
CommerceErrorEvents contains information about the validation error, such as field name,
field label, and error message. CommerceActionEvents is not an event that the developer’s
code should listen for in checkout either, as it is not related to troubleshooting or
responding to actions. CommerceActionEvents is an event that is fired by Salesforce B2B
Commerce when a user performs an action in the storefront. CommerceActionEvents
contains information about the user action, such as action name, action type, and action
Northern Tail Outfitters (NTO) is converting an existing aura component into a LightningWeb Component. The aura component has the following source code:
C)
A. Option A B. Option B C. Option C D. Option D
Answer: B
Explanation:
The equivalent of this code in a Lightning web component is option B. Option B uses the
@api decorator to expose firstName as a public property of the Lightning web component
and communicate it with other components or services. The @api decorator is a decorator
that marks a property or method as public, which means that it can be accessed by other
components or services that use or consume this component. The @api decorator also
makes the property reactive, which means that it can track changes and update the
component accordingly. In option B, firstName is exposed as a public property using the
@api decorator and passed to the child element using an attribute. Option A is incorrect
because it uses an invalid syntax for exposing firstName as a public property. The @api
decorator should be used before the property declaration, not after it. Option C is incorrect
because it uses an invalid syntax for exposing firstName as a public property. The @api
decorator should be used with parentheses, not without them. Option D is incorrect
because it uses an invalid syntax for exposing firstName as a public property. The @api
decorator should be used with camel case, not with hyphens. Salesforce References:

Question # 46
A developer has created a custom Lightning web component to display on the ProductDetail page in the store. When the developer goes to add the component to the page inExperience Builder, it is missing from the list of custom components.Which XML fragment should the developer include in the component's configuration XMLfile to ensure the custom component is available to add to the page?
A. Option A B. Option B C. Option C D. Option D
Answer: B
Explanation:
The XML fragment that the developer should include in the component’s configuration XML
file to ensure the custom component is available to add to the page is option B. Option B
uses the <targets> tag to specify where the component can be used in an app. The
<targets> tag contains a list of <target> tags, each of which defines a valid target for the
component. The value of the <target> tag for the Product Detail page in the store is
lightningCommunity__RecordPage, which means that the component can be used on any
record page in a Lightning community. Option A is incorrect because it uses an invalid
value for the <target> tag. There is no such target as
lightningCommunity__ProductDetailPage. Option C is incorrect because it uses an invalid
syntax for the <targets> tag. The <targets> tag should not have any attributes, such as
isAvailable. Option D is incorrect because it uses an invalid syntax for the <target> tag. The
<target> tag should not be self-closing, but rather have a closing tag (</target>). Salesforce

Question # 47
How should a developer get the grand total amount, including shipping and tax, for items inthecart and in the currency of the cart, when developing a new Lightning web component foranAura storefront cart page?
A. {!Cart.Details.grandTotal} B. {ICart.Totals.grand Total} C. {ICart.Details.Fields.grandTotal} D. {!Cart.Fields.grandTotal}
Answer: C
Explanation: According to the B2B Commerce Developer Guide, the ICart interface
provides access to the cart object and its related data. The Details property of the ICart
interface returns an ICartDetails object, which contains information about the cart such as
the currency, the subtotal, the shipping cost, the tax, and the grand total. The Fields
property of the ICartDetails interface returns a map of field names and values for the cart
object. Therefore, to get the grand total amount for items in the cart and in the currency of
the cart, a developer should use the expression {ICart.Details.Fields.grandTotal}, which
returns the value of the grandTotal field from the cart object. References: B2B Commerce
Which two guidelines should a developer consider when migrating aura components toLWC?
A. Migrate one component and then determine whether additional effort would make sense B. Start with migrating trees of components (components within components) C. Force all developers to write any new components using Lightning web components D. Start with simple components that only render Ul
Answer: A,D
Explanation:
When migrating aura components to LWC, a developer should consider two guidelines:
migrate one component and then determine whether additional effort would make sense
and start with simple components that only render UI. Migrating one component and then
determining whether additional effort would make sense allows the developer to evaluate
the benefits and costs of migration and decide whether to continue or stop. Migrating
simple components that only render UI allows the developer to leverage the performance
and modern features of LWC without much complexity or dependency on other
components or services. Starting with migrating trees of components (components within
components) is not a good guideline, as it can introduce more challenges and
dependencies that can complicate the migration process. Forcing all developers to write
any new components using Lightning web components is not a good guideline either, as it
can create inconsistency and confusion among developers and users. Salesforce

Question # 49
Universal Containers (UC) is ready to build a tax provider class using the interfacesavailable in the Buyer Experience SDK. When creating a tax provider, what are three thingsthat a developer should consider first?
A. Steps to complete in the Tax Service B. How to handle results C. WhethertouseJSONorXML D. What to implement E. What events to fire in the Lightning web component
Answer: A,B,D
Explanation:
When creating a tax provider, three things that a developer should consider first are: steps
to complete in the tax service, how to handle results, and what to implement. Steps to
complete in the tax service are the actions that the developer needs to perform to connect
to and use the third-party tax service provider’s API or service. These steps may include
authentication, authorization, request formatting, response parsing, error handling, and
logging. How to handle results are the actions that the developer needs to perform to
process and apply the tax calculation results from the tax service to the cart or order.
These actions may include creating or updating cart items with type of Charge and charge
type of Tax, applying tax adjustments or exemptions, and displaying tax amounts and
details on the storefront. What to implement are the methods that the developer needs to
define in their custom Apex class that implements the sfdc_checkout.TaxCalculations
interface. The interface provides methods for customizing the tax calculation logic for a cart or an order, such as getTaxRatesAndRules, applyTaxAmountsAndAdjustments, and
handleTaxErrorsAndExceptions. Whether to use JSON or XML is not something that the
developer should consider first, as it is not a critical or relevant factor for creating a tax
provider. It may depend on the format that the tax service provider supports or prefers, but
it does not affect the overall functionality or performance of the tax integration. What events
to fire in the Lightning web component is not something that the developer should consider
first either, as it is not related to creating a tax provider. It may be an optional feature that
the developer can add to enhance the user interface or user experience of their storefront,
but it does not affect the core logic or functionality of the tax integration. Salesforce
Which two methods from the platformResourceLoader module are relevant for includingthird party JavaScript and CSS in a Lightning web component?
A. loadClientScript B. loadScript C. loadCss D. loadStyle
Answer: B,D
Explanation: Two methods from the platformResourceLoader module that are relevant for
including third party JavaScript and CSS in a Lightning web component are loadScript and
loadStyle. The platformResourceLoader module is a module that provides methods for
loading JavaScript or CSS files from static resources or external URLs into a Lightning web
component. The loadScript method is used to load a JavaScript file and execute it in the
component. The loadStyle method is used to load a CSS file and apply it to the component.
The loadClientScript method does not exist or is not relevant for including third party
JavaScript in a Lightning web component. The loadCss method does not exist or is not
relevant for including third party CSS in a Lightning web component. Salesforce

Question # 51
A developer is working on a storefront that needs to use a sophisticated pricing enginehosted as a service outside the org. Assuming security and trusts have been established,which two actions must the developer take?
A. Make a call to the service B. Use External Ohjects C. Implement the sfdc_checkout.PriceCalculations D. Implement the sfdc_checkout.CartPriceCalculations
Answer: A,C
Explanation:
The correct answer is A and C. To use a sophisticated pricing engine hosted as a
service outside the org, the developer must make a call to the service and
implement the sfdc_checkout.PriceCalculations interface12. The
sfdc_checkout.PriceCalculations interface is a standard interface that defines the
methods for calculating prices for a cart or an order1. The developer can use this
interface to override the default pricing logic and integrate with an external pricing
service12. The developer must also make a call to the external service using Apex
REST or SOAP callouts3 and handle the response data accordingly.
Use External Objects and Implement the sfdc_checkout.CartPriceCalculations are
not the correct answers. External objects are a way to access data from external
data sources in real time, but they are not suitable for integrating with a pricing
service that requires dynamic calculations . The
sfdc_checkout.CartPriceCalculations interface is a deprecated interface that was
used for calculating prices for a cart only1. It has been replaced by the
sfdc_checkout.PriceCalculations interface, which supports both carts and
orders1. References:

Question # 52
In a B2B Commerce store, which three tasks must a developer complete to implement the use of a third-party service for either tax, shipping, or pricing calculation?
A. Register an Apex class as the integration in the store administration B. Create a flow to call the external service directly C. Create an Apex class implementing the appropriate interface. D. Create a named credential for authentication with an external service E. Create an Apex class with an invocable method
Answer: A,C,D
Explanation: To implement the use of a third-party service for either tax, shipping, or
pricing calculation in a B2B Commerce store, a developer must complete these three tasks:
Create an Apex class that implements the appropriate interface for the calculation
type. For example, for tax calculation, the developer must implement the
sfdc_checkout.CartTax interface and define the getTax method. This method takes
a Cart object as an input parameter and returns a list of CartTax objects with the
calculated tax amounts.
Create a named credential for authentication with the external service. A named
credential specifies the URL of a callout endpoint and its required authentication
parameters. The developer can use the named credential in the Apex class to
make the callout to the external service and handle the response.
Register the Apex class as the integration in the store administration. The
developer must specify the Apex class name in the corresponding field for the
calculation type. For example, for tax calculation, the developer must enter the
Apex class name in the Tax Calculation Integration field. This way, the store can
invoke the Apex class to perform the calculation for each cart.
The other options are not valid tasks for implementing the use of a third-party service.
Creating a flow to call the external service directly is not supported for B2B Commerce, and
creating an Apex class with an invocable method is not required for the calculation
integration. References:

Question # 53
Which technique can be used with Lightning web components to expose them outside ofan org in another web container?
A. Slot elements B. Heroku C. Lightning Out D. Lightning Canvas
Answer: C
Explanation: According to the Lightning Web Components Developer Guide, Lightning Out
is a technique that allows developers to run Lightning web components outside of
Salesforce servers, such as in a Node.js app running on Heroku or a department server
inside the firewall. Lightning Out uses a script tag to load the Lightning web components
framework and the custom components into the web container. Lightning Out also handles
authentication, event handling, and data access between the web container and the
Salesforce org. Slot elements, Heroku, and Lightning Canvas are not techniques for
exposing Lightning web components outside of an org in another web
container. References: Lightning Web Components Developer Guide, Use Components

Question # 54
How should data for Lightning web components be provided?
A. A few properties that contain sets (objects) of data B. One property that contains all data in one set (object) C. A single property object that contains sets (objects) of data D. Independent properties that take simpler, primitive values (e.g. String, Number, Boolean,Array)
Answer: D
Explanation: Data for Lightning web components should be provided as independent
properties that take simpler, primitive values (e.g. String, Number, Boolean, Array).
Providing data as independent properties allows the developer to expose data as public or
private properties of the Lightning web component and communicate data between
components or services. Providing data as simpler, primitive values allows the developer to
use data types that are supported by JavaScript and Lightning web components and avoid
unnecessary or complex conversions or transformations. Providing data as a few
properties that contain sets (objects) of data is not a good way to provide data for Lightning
web components, as it can create confusion or inconsistency in data structure and access.
Providing data as one property that contains all data in one set (object) is not a good way
either, as it can create complexity or inefficiency in data management and manipulation.
Providing data as a single property object that contains sets (objects) of data is not a good
way either, as it can create redundancy or duplication in data storage and retrieval.

Question # 55
A developer needs to create an event listener on a parent component programmaticallv.With the script below, what should replace the text <EVENT LISTENER UNE>?
A. this.template.addEventListener(handleNotification); B. this.template.addEventListener(this.handleNotification); C. this.template.addEventListenerCnotification1, this.handleNotification); D. addEventListener('notifJcatiorV, this.handleNotification);
Answer: C
Explanation: To create an event listener on a parent component programmatically, the
This line of code adds an event listener to the template element of the parent component,
which is the root element that contains all the child elements. The event listener listens for
an event named ‘notification’, which is a custom event that can be dispatched by any child
component. The event listener invokes a method named handleNotification, which is an
arrow function defined in the parent component class. The handleNotification method
receives the event object as a parameter and can perform any logic based on the event
data. The other lines of code are either incorrect or incomplete. Salesforce References:

Question # 56
A developer is setting up a storefront from scratch. They need to create a storefront, pushstore sources, create buyer users, import products, and create and search index.Which command allows the developer to accomplish this task?
A. sfdx commerce:store:quickstart:create -templatename 'b2c-lite-storefront’ B. sfdx commerce:store:quickstart:setup —definitionfile store-scratch-def json C. sfdx commerce:store:create —store-name test-store D. sfdx commerce:store:open —store-name test-store
Answer: B
Explanation: The sfdx commerce:store:quickstart:setup command allows the developer to
set up a store from scratch using a definition file that specifies the store configuration. This
command performs the following tasks:
Pushes the store sources to the scratch org
Creates a buyer user
Imports products
Creates a search index
Opens the store in a browser
The other options are not correct because:
A. sfdx commerce:store:quickstart:create only creates a community for the store,
but does not perform the other tasks required to set up a store from scratch.
C. sfdx commerce:store:create creates and sets up a store, but does not use a
definition file to specify the store configuration. Instead, it uses command-line flags
to provide the store parameters.
D. sfdx commerce:store:open only opens an existing store in a browser, but does
not create or set up a store from scratch.

Question # 57
A developer is on a tight timeline and needs to implement a Lightning web componentwhich can read, create and modify single records. What is the recommended path forward?
A. Use base components B. Write custom functions against a wire adapter C. Create an Apex Controller D. Use Lightning Data Service
Answer: D
Explanation: To implement a Lightning web component which can read, create and modify
single records, the recommended path forward is to use Lightning Data Service. Lightning
Data Service is a service that provides access to Salesforce data and metadata, cache
management, and data synchronization across components. Lightning Data Service allows
developers to use standard components or base components to perform CRUD (create,
read, update, delete) operations on single records without writing Apex code or SOQL
queries. Lightning Data Service also handles data caching, performance optimization, and
conflict resolution automatically. Using base components is not a sufficient way to
implement a Lightning web component which can read, create and modify single records,
as base components are only user interface elements that do not provide data access or
manipulation functionality by themselves. Base components need to be used with Lightning
Data Service or other services to perform CRUD operations on single records. Writing
custom functions against a wire adapter is not a recommended way to implement a
Lightning web component which can read, create and modify single records, as it involves
writing complex and error-prone JavaScript code that may not be efficient or scalable.
Writing custom functions against a wire adapter also requires handling data caching,
performance optimization, and conflict resolution manually. Creating an Apex controller is
not a recommended way either, as it involves writing Apex code that may not be necessary
or optimal for performing CRUD operations on single records. Creating an Apex controller
also requires exposing Apex methods using @AuraEnabled or @RemoteAction
annotations and invoking them from JavaScript code using imperative calls or promises.

Question # 58
What are two purposes of the Shadow DOM in a Lightning web component?
A. It encapsulates the internal document object model (DOM) structure of a webcomponent B. It allow components to be shared while protecting them from being manipulated byarbitrary code C. It allows direct access to the document object model of the component D. It allows older JavaScript libraries to manipulate the tagging structure
Answer: A,B
Explanation: According to the Lightning Web Components Developer Guide, Shadow
DOM is a standard that encapsulates the internal document object model (DOM) structure
of a web component. Encapsulating the DOM gives developers the ability to share a
component and protect the component from being manipulated by arbitrary HTML, CSS,
and JavaScript. Shadow DOM also provides style and behavior isolation for a web
component, which means that the styles and scripts defined inside a component do not
affect the rest of the page, and vice versa. Therefore, the purposes of the Shadow DOM in
a Lightning web component are to encapsulate the internal DOM structure of a web component (A) and to allow components to be shared while protecting them from being
manipulated by arbitrary code (B). The other options are incorrect because Shadow DOM
allow older JavaScript libraries to manipulate the tagging structure
(D). References: Lightning Web Components Developer Guide, Understand the Shadow

What is likely to happen if a developer leaves debug mode turned on in an environment?
A. The performance of the org will become slower each day B. The user will begin getting JavaScript limit exceptions C. The org will turn off debug mode after 72 hours D. A banner will be displayed to the user indicating that the org is in debug mode
Answer: B
Explanation:
If a developer leaves debug mode turned on in an environment, the user will begin getting
JavaScript limit exceptions. Debug mode is a setting that enables more detailed logging
and error reporting for Lightning web components. However, it also increases the size and
complexity of the JavaScript code that is delivered to the browser, which can cause
performance issues and JavaScript limit exceptions. The JavaScript limit exceptions are
errors that occur when the browser reaches its maximum capacity for executing JavaScript
code, such as memory heap size or script execution time. The performance of the org will
not become slower each day, as debug mode only affects the client-side performance, not
the server-side performance. The org will not turn off debug mode after 72 hours, as debug
mode is a persistent setting that can only be changed manually by an administrator. A
banner will not be displayed to the user indicating that the org is in debug mode, as debug
mode is a transparent setting that does not affect the user interface. Salesforce

Question # 61
A developer exports data from an org on a standard entity which has a custom attribute. When they launch Data Loader, select the entity, click the Select All Fields button and clickFinish, the custom field they added called MyCustomField_c has no values and no columnheader in the CSV file. What is the root cause?
A. The user needs to install a specific Zulu JDK that is recommended by Salesforce. B. A mapping file was not used when the data was loaded in C. The user does not have access to the field D. The user has rights to the field but there are no values in it
Answer: C
Explanation:
The root cause of why the custom field MyCustomField__c has no values and no column
header in the CSV file is that the user does not have access to the field. A user’s access to
a field is determined by their profile and permission sets, which define their field-level
security settings. Field-level security settings control whether a user can see, edit, or delete
the value for a particular field on an object. If a user does not have access to a field, they
will not be able to view or modify its value in any interface, including Data Loader. Data
Loader is a tool that allows users to import or export data between Salesforce and CSV
files. When using Data Loader to export data from an org, Data Loader will only include
fields that are accessible to the user based on their field-level security settings. If a user
does not have access to a field, Data Loader will not include that field in the CSV file,
neither as a column header nor as a value. The user needs to install a specific Zulu JDK
that is recommended by Salesforce is not the root cause of why MyCustomField__c has no
values and no column header in the CSV file, as it is not related to field access or Data
Loader functionality. A mapping file was not used when the data was loaded in is not the
root cause either, as it is not related to field access or Data Loader functionality. A mapping
file is an optional file that maps fields between Salesforce objects and CSV files when
using Data Loader to import or export data. The user has rights to the field but there are no
values in it is not the root cause either, as it contradicts the fact that MyCustomField__c
has no column header in the CSV file. If the user had rights to the field but there were no
values in it, Data Loader would still include MyCustomField__c as a column header in the
CSV file, but leave its values blank. Salesforce References: [Data Loader Guide: Export

Level Security]
Question # 62
Which practice is allowed when it comes to naming a Lightning web component's folderand associated files?
A. Including whitespace B. Using a single underscore C. Using consecutive underscores D. Using a single hyphen (dash)
Answer: D
Explanation: To name a Lightning web component’s folder and associated files, the
developer should follow these naming rules:
Must begin with a lowercase letter
Must contain only alphanumeric or underscore characters
Must be unique in the namespace
Can’t include whitespace
Can’t end with an underscore
Can’t contain two consecutive underscores
Can’t contain a hyphen (dash) The only exception to the last rule is when separating the namespace from the component
name in markup. For example, if the component is in the example namespace and has the
name myComponent, the folder name should be myComponent, but the markup tag should
be <example-my-component>. The hyphen character (-) is required by the HTML standard
for custom element names. The other options are either invalid or not recommended. For
example, including whitespace or using consecutive underscores will cause errors, and
using a single underscore will look odd and may confuse developers consuming the
component. References: B2B Commerce and D2C Commerce Developer Guide, Lightning

Question # 63
What two things happen with the Cart during tax implementation?
A. New entries are written to the Cart B. Previous entries are copied to another object C. Previous entries are deleted from the Cart D. New entries are written to the Order Summary
Answer: A,C
Explanation: Two things that happen with the cart during tax implementation are that new
entries are written to the cart and previous entries are deleted from the cart. A tax
implementation is an integration that calculates and applies tax rates and amounts to a cart
or an order based on various factors, such as product type, price, quantity, location, and
tax rules. A tax implementation can use either an external tax service provider or custom
Apex code to perform the tax calculation. When a tax implementation is invoked for a cart,
it writes new entries to the cart with a type of Charge and a charge type of Tax. These
entries represent the tax amounts and adjustments that are applied to the cart. Before
writing new entries to the cart, the tax implementation deletes any existing entries with a
type of Charge and a charge type of Tax from the cart. This ensures that the tax calculation
is accurate and up-to-date based on the current state of the cart and avoids any conflicts or
inconsistencies with previous tax entries. Previous entries are not copied to another object
or modified with the new tax calculation, as these are not valid actions for handling existing
Which three components should a developer use on the product page to replace the out-ofthe-box Product Detail Card component?
A. Product Detail Breadcrumbs component B. Product Fields Short component C. Product Field Long component D. Product Detail Purchase Options component E. Product Detail Image Gallery component

Explanation: The Product Detail Card component is a standard component that displays
the product information and options on the product page. It includes the following
elements1:
