A developer suspects recent edits to a checkout flow have created a bug based on flow errors being emailed. Given the emails and some inputs known to trigger the issue, which two 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 previousversions of the flow with the current one can help identify changes that might haveintroduced the bug. Additionally, Salesforce provides debugging capabilities within the FlowBuilder, where a developer can select the debug option, provide input values known totrigger the issue, and execute the flow to observe its behavior, aiding in pinpointing thesource 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 Auracomponent can contain a Lightning Web Component. This interoperability allows for asmoother transition from Aura to LWC and enables developers to utilize the strengths ofboth frameworks. However, nesting a Lightning Web Component within an Auracomponent which in turn contains a Lightning Web Component (Option C) is not a standardpractice. For more information, refer to the Salesforce documentation on using Aura andLightning Web Components together:Salesforce Aura and LWC InteroperabilityDocumentation.
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 asequence, a developer must adjust the 'next-state' attribute in the configuration of thepreceding subflow. This approach allows for dynamic control over the sequence ofcheckout steps without needing to modify the structure of the main checkout flow itself. TheSalesforce B2B Commerce documentation outlines how checkout flows are constructedand 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 Flowsand Apex Triggers. This allows for the execution of automated processes in response tothe events. Apex Triggers can be written to respond to event messages in the same waythey respond to DML events. Similarly, Flows can be configured to trigger upon the receiptof a platform event. This functionality is documented in Salesforce's developer guides andbest practices, which emphasize the versatility and power of combining declarative andprogrammatic approaches to respond to platform events.
Question # 5
What is one requirement to keep in mind when including additional JavaScript 1h files in a Lightning 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 thatthese files are ECMAScript 6 (ES6) modules and have unique names within thecomponent's folder. This ensures proper module resolution and avoids namespaceconflicts. Salesforce LWC documentation provides guidelines on organizing componentresources, including JavaScript modules, to ensure they are correctly recognized andutilized within the LWC framework.

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 withsales prices for cart items and finds them to be the same, the appropriate return valueshould indicate a successful comparison (such assfdc_checkout.IntegrationStatus.Status.SUCCESS). This signifies that the externalprices 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 SalesforceB2B Commerce, previous tax entries are usually preserved or saved before anyrecalculation is performed. This ensures that there is a record of the original taxcalculations before any modifications, which can be crucial for auditing, historical dataintegrity, 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 withinthe component's template where content can be inserted dynamically. This feature, part ofthe Web Components standard, allows for the creation of customizable and reusablecomponents. Salesforce developer documentation on LWC outlines the use of slots to buildflexible component interfaces, enabling developers to design components that can adapt tovarious 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 themetadata of a specified Salesforce object, including fields, record types, and layouts, whichis 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 creating the HTML markup and receives an error. Which three tags when used as the first element in 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 frameworkrequires<template>as the root tag. The<template>tag is necessary for defining thecomponent'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 errorduring component compilation or runtime. Refer to the Salesforce LWC documentation forproper component structure:Salesforce LWC Component Structure Documentation.
Question # 17
Which tool is used to retrieve and manipulate Salesforce data in a Lightning Web Component?
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 andmanipulate Salesforce data. Wire adapters abstract the underlying data accessmechanism, providing a declarative way to access Salesforce data and metadata.Salesforce documentation on LWC and the@wiredecorator details how wire adapters canbe used to connect components to Salesforce data sources, including standard and customobjects, 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 handledare programmatically adding event listeners and attaching handlers to DOM elements.Programmatically adding event listeners is a way of handling events by using JavaScriptcode to register functions that are invoked when an event occurs. The developer can usemethods such as addEventListener or @wire to add event listeners to components orservices that fire events. Attaching handlers to DOM elements is a way of handling eventsby using HTML attributes to bind functions that are invoked when an event occurs. Thedeveloper can use attributes such as onclick or onchange to attach handlers to DOMelements that fire events. Adding callbacks to components is not a valid way of handlingevents fired from Lightning web components, as it is not related to event handling, butrather to asynchronous programming. Listening for all possible events at the document rootis not a valid way either, as it is not efficient or recommended for event handling, as it cancause performance issues or conflicts with other event listeners. Salesforce References:[Lightning WebComponents Developer Guide: Handle Events], [Lightning WebComponents Developer Guide: Communicate with Events]
Question # 19
A developer suspects that a defect exists in 30 lines of Apex code. How can the developer add debug statements, run the block of apex code in isolation and observe the immediate results?

A developer needs to bulk export all of the Product data from an org and does not have access to Data Loader or Workbench. However, the Command Line Interface (CLI) is available. 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 exportdata from an org into one or more JSON files1. The -q flag is used to specify the path to afile containing a SOQL query, -x is used to specify the name of the exported file, -d is usedto specify the directory where the exported file will be saved, and -p is used to indicate thatall records returned by the SOQL query should be exported12. This command allowsdevelopers to bulk export data from an org without needing access to Data Loader orWorkbench12. Therefore, option A is the correct answer. Please note that the actual SOQLquery and the directory path would need to be replaced with the appropriate values for thespecific use case.
Question # 38
Which three are considered code units, or discrete units of work within a transaction in the debug 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 unitsof work within a transaction. Apex classes (B), Web service invocations (C), and Workflowinvocations (E) are considered code units as they encapsulate specific operations or setsof logic that can be executed as part of a transaction. Validation rules (A) and the loading ofLightning components (D) are not considered discrete units of work in the same way, asthey are part of the declarative interface and front-end framework, respectively. For moredetails on how Salesforce handles transactions and debug logs, refer to the SalesforceDeveloper Documentation:Salesforce Developer Documentation on Transactions andDebug Logs.

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@wireplaycrucial roles. The@apidecorator is used to expose public properties and methods, makingthem accessible to other components. The@trackdecorator is used to mark privateproperties as reactive, so the UI updates when their values change. The@wiredecorator isused to wire Apex methods or Salesforce data to the component. Salesforcedocumentation on LWC development extensively covers these decorators, explaining theirusage and best practices.
Question # 44
In checkout, what event should the developer's code listen for in order to help troubleshoot and 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’scode should listen for CommerceDiagnosticEvents. CommerceDiagnosticEvents is anevent that is fired by Salesforce B2B Commerce when an error occurs in the storefront.CommerceDiagnosticEvents contains information about the error, such as error code, errormessage, error type, and error details. CommerceDiagnosticEvents can be subscribed byother components or services that want to handle or display the error information indifferent ways. The developer’s code can listen for CommerceDiagnosticEvents usingan 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 customlogic 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 incheckout, as it is not related to troubleshooting or responding to actions.CommerceBubbleEvents is an event that is fired by Salesforce B2B Commerce when auser interacts with a bubble component in the storefront. A bubble component is a userinterface element that displays information or options in a pop-up window when clicked orhovered over. CommerceBubbleEvents contains information about the user interaction,such as bubble name, bubble type, and bubble value. CommerceErrorEvents is not anevent that the developer’s code should listen for in checkout either, as it is not related totroubleshooting or responding to actions. CommerceErrorEvents is an event that is fired bySalesforce 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’scode should listen for in checkout either, as it is not related to troubleshooting orresponding to actions. CommerceActionEvents is an event that is fired by Salesforce B2BCommerce when a user performs an action in the storefront. CommerceActionEventscontains information about the user action, such as action name, action type, and actionparameters.

Question # 45
Northern Tail Outfitters (NTO) is converting an existing aura component into a Lightning Web 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 componentand communicate it with other components or services. The @api decorator is a decoratorthat marks a property or method as public, which means that it can be accessed by othercomponents or services that use or consume this component. The @api decorator alsomakes the property reactive, which means that it can track changes and update thecomponent 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 incorrectbecause it uses an invalid syntax for exposing firstName as a public property. The @apidecorator should be used before the property declaration, not after it. Option C is incorrectbecause it uses an invalid syntax for exposing firstName as a public property. The @apidecorator should be used with parentheses, not without them. Option D is incorrectbecause it uses an invalid syntax for exposing firstName as a public property. The @apidecorator should be used with camel case, not with hyphens.

Question # 46
A developer has created a custom Lightning web component to display on the Product Detail page in the store. When the developer goes to add the component to the page in Experience Builder, it is missing from the list of custom components. Which XML fragment should the developer include in the component's configuration XML file 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 XMLfile to ensure the custom component is available to add to the page is option B. Option Buses 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 thecomponent. The value of the <target> tag for the Product Detail page in the store islightningCommunity__RecordPage, which means that the component can be used on anyrecord page in a Lightning community. Option A is incorrect because it uses an invalidvalue for the <target> tag. There is no such target aslightningCommunity__ProductDetailPage. Option C is incorrect because it uses an invalidsyntax for the <targets> tag. The <targets> tag should not have any attributes, such asisAvailable. 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>).

Question # 47
How should a developer get the grand total amount, including shipping and tax, for items in the cart and in the currency of the cart, when developing a new Lightning web component for an Aura 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 interfaceprovides access to the cart object and its related data. The Details property of the ICartinterface returns an ICartDetails object, which contains information about the cart such asthe currency, the subtotal, the shipping cost, the tax, and the grand total. The Fieldsproperty of the ICartDetails interface returns a map of field names and values for the cartobject. Therefore, to get the grand total amount for items in the cart and in the currency ofthe cart, a developer should use the expression {ICart.Details.Fields.grandTotal}, whichreturns the value of the grandTotal field from the cart object.

Question # 48
Which two guidelines should a developer consider when migrating aura components to LWC?
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 senseand start with simple components that only render UI. Migrating one component and thendetermining whether additional effort would make sense allows the developer to evaluatethe benefits and costs of migration and decide whether to continue or stop. Migratingsimple components that only render UI allows the developer to leverage the performanceand modern features of LWC without much complexity or dependency on othercomponents or services. Starting with migrating trees of components (components withincomponents) is not a good guideline, as it can introduce more challenges anddependencies that can complicate the migration process. Forcing all developers to writeany new components using Lightning web components is not a good guideline either, as itcan create inconsistency and confusion among developers and users.

Question # 49
Universal Containers (UC) is ready to build a tax provider class using the interfaces available in the Buyer Experience SDK. When creating a tax provider, what are three things that 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: stepsto complete in the tax service, how to handle results, and what to implement. Steps tocomplete in the tax service are the actions that the developer needs to perform to connectto and use the third-party tax service provider’s API or service. These steps may includeauthentication, authorization, request formatting, response parsing, error handling, andlogging. How to handle results are the actions that the developer needs to perform toprocess 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 chargetype of Tax, applying tax adjustments or exemptions, and displaying tax amounts anddetails on the storefront. What to implement are the methods that the developer needs todefine in their custom Apex class that implements the sfdc_checkout.TaxCalculationsinterface. The interface provides methods for customizing the tax calculation logic for a cart or an order, such as getTaxRatesAndRules, applyTaxAmountsAndAdjustments, andhandleTaxErrorsAndExceptions. Whether to use JSON or XML is not something that thedeveloper should consider first, as it is not a critical or relevant factor for creating a taxprovider. It may depend on the format that the tax service provider supports or prefers, butit does not affect the overall functionality or performance of the tax integration. What eventsto fire in the Lightning web component is not something that the developer should considerfirst either, as it is not related to creating a tax provider. It may be an optional feature thatthe 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.

Question # 50
Which two methods from the platformResourceLoader module are relevant for including third 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 forincluding third party JavaScript and CSS in a Lightning web component are loadScript andloadStyle. The platformResourceLoader module is a module that provides methods forloading JavaScript or CSS files from static resources or external URLs into a Lightning webcomponent. The loadScript method is used to load a JavaScript file and execute it in thecomponent. 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 partyJavaScript in a Lightning web component. The loadCss method does not exist or is notrelevant for including third party CSS in a Lightning web component.

Question # 51
A developer is working on a storefront that needs to use a sophisticated pricing engine hosted 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 aservice outside the org, the developer must make a call to the service andimplement the sfdc_checkout.PriceCalculations interface12. Thesfdc_checkout.PriceCalculations interface is a standard interface that defines themethods for calculating prices for a cart or an order1. The developer can use thisinterface to override the default pricing logic and integrate with an external pricingservice12. The developer must also make a call to the external service using ApexREST or SOAP callouts3 and handle the response data accordingly.Use External Objects and Implement the sfdc_checkout.CartPriceCalculations arenot the correct answers. External objects are a way to access data from externaldata sources in real time, but they are not suitable for integrating with a pricingservice that requires dynamic calculations . Thesfdc_checkout.CartPriceCalculations interface is a deprecated interface that wasused for calculating prices for a cart only1. It has been replaced by thesfdc_checkout.PriceCalculations interface, which supports both carts andorders1.

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 calculationtype. For example, for tax calculation, the developer must implement thesfdc_checkout.CartTax interface and define the getTax method. This method takesa Cart object as an input parameter and returns a list of CartTax objects with thecalculated tax amounts.Create a named credential for authentication with the external service. A namedcredential specifies the URL of a callout endpoint and its required authenticationparameters. The developer can use the named credential in the Apex class tomake the callout to the external service and handle the response.Register the Apex class as the integration in the store administration. Thedeveloper must specify the Apex class name in the corresponding field for thecalculation type. For example, for tax calculation, the developer must enter theApex class name in the Tax Calculation Integration field. This way, the store caninvoke 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, andcreating an Apex class with an invocable method is not required for the calculationintegration.

Question # 53
Which technique can be used with Lightning web components to expose them outside of an 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 Outis a technique that allows developers to run Lightning web components outside ofSalesforce servers, such as in a Node.js app running on Heroku or a department serverinside the firewall. Lightning Out uses a script tag to load the Lightning web componentsframework and the custom components into the web container. Lightning Out also handlesauthentication, event handling, and data access between the web container and theSalesforce org. Slot elements, Heroku, and Lightning Canvas are not techniques forexposing Lightning web components outside of an org in another webcontainer.

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 independentproperties that take simpler, primitive values (e.g. String, Number, Boolean, Array).Providing data as independent properties allows the developer to expose data as public orprivate properties of the Lightning web component and communicate data betweencomponents or services. Providing data as simpler, primitive values allows the developer touse data types that are supported by JavaScript and Lightning web components and avoidunnecessary or complex conversions or transformations. Providing data as a fewproperties that contain sets (objects) of data is not a good way to provide data for Lightningweb 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 wayeither, 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 goodway either, as it can create redundancy or duplication in data storage and retrieval.Salesforce References: Lightning Web Components Developer Guide: Communicate withProperties, Lightning Web Components Developer Guide: Data Types
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, thedeveloper should use the following line of code:this.template.addEventListener(‘notification’, this.handleNotification);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 foran event named ‘notification’, which is a custom event that can be dispatched by any childcomponent. The event listener invokes a method named handleNotification, which is anarrow function defined in the parent component class. The handleNotification methodreceives the event object as a parameter and can perform any logic based on the eventdata. The other lines of code are either incorrect or incomplete.

Question # 56
A developer is setting up a storefront from scratch. They need to create a storefront, push store 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 toset up a store from scratch using a definition file that specifies the store configuration. Thiscommand performs the following tasks:Pushes the store sources to the scratch orgCreates a buyer userImports productsCreates a search indexOpens the store in a browserThe 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 adefinition file to specify the store configuration. Instead, it uses command-line flagsto provide the store parameters.D. sfdx commerce:store:open only opens an existing store in a browser, but doesnot create or set up a store from scratch.References:store CommandsBuild a B2B and B2B2C Commerce Store
Question # 57
A developer is on a tight timeline and needs to implement a Lightning web component which 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 modifysingle records, the recommended path forward is to use Lightning Data Service. LightningData Service is a service that provides access to Salesforce data and metadata, cachemanagement, and data synchronization across components. Lightning Data Service allowsdevelopers to use standard components or base components to perform CRUD (create,read, update, delete) operations on single records without writing Apex code or SOQLqueries. Lightning Data Service also handles data caching, performance optimization, andconflict resolution automatically. Using base components is not a sufficient way toimplement 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 ormanipulation functionality by themselves. Base components need to be used with LightningData Service or other services to perform CRUD operations on single records. Writingcustom functions against a wire adapter is not a recommended way to implement aLightning web component which can read, create and modify single records, as it involveswriting 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 isnot a recommended way either, as it involves writing Apex code that may not be necessaryor optimal for performing CRUD operations on single records. Creating an Apex controlleralso requires exposing Apex methods using @AuraEnabled or @RemoteActionannotations and invoking them from JavaScript code using imperative calls or promises.Salesforce References: Lightning Web Components Developer Guide: Access Salesforce Data, Lightning Web Components Developer Guide: Base Components, [Lightning WebComponents Developer Guide: Call Apex Methods]
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

Question # 60
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 gettingJavaScript limit exceptions. Debug mode is a setting that enables more detailed loggingand error reporting for Lightning web components. However, it also increases the size andcomplexity of the JavaScript code that is delivered to the browser, which can causeperformance issues and JavaScript limit exceptions. The JavaScript limit exceptions areerrors that occur when the browser reaches its maximum capacity for executing JavaScriptcode, such as memory heap size or script execution time. The performance of the org willnot become slower each day, as debug mode only affects the client-side performance, notthe server-side performance. The org will not turn off debug mode after 72 hours, as debugmode is a persistent setting that can only be changed manually by an administrator. Abanner will not be displayed to the user indicating that the org is in debug mode, as debugmode is a transparent setting that does not affect the user interface. SalesforceReferences: Lightning Web Components Developer Guide: Debug Your Code, LightningWeb Components Developer Guide: JavaScript Limit Exceptions
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 column header 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 columnheader in the CSV file is that the user does not have access to the field. A user’s access toa field is determined by their profile and permission sets, which define their field-levelsecurity settings. Field-level security settings control whether a user can see, edit, or deletethe value for a particular field on an object. If a user does not have access to a field, theywill not be able to view or modify its value in any interface, including Data Loader. DataLoader is a tool that allows users to import or export data between Salesforce and CSVfiles. When using Data Loader to export data from an org, Data Loader will only includefields that are accessible to the user based on their field-level security settings. If a userdoes 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 JDKthat is recommended by Salesforce is not the root cause of why MyCustomField__c has novalues and no column header in the CSV file, as it is not related to field access or DataLoader functionality. A mapping file was not used when the data was loaded in is not theroot cause either, as it is not related to field access or Data Loader functionality. A mappingfile is an optional file that maps fields between Salesforce objects and CSV files whenusing Data Loader to import or export data. The user has rights to the field but there are novalues in it is not the root cause either, as it contradicts the fact that MyCustomField__chas no column header in the CSV file. If the user had rights to the field but there were novalues in it, Data Loader would still include MyCustomField__c as a column header in theCSV file, but leave its values blank.

Question # 62
Which practice is allowed when it comes to naming a Lightning web component's folder and 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, thedeveloper should follow these naming rules:Must begin with a lowercase letterMust contain only alphanumeric or underscore charactersMust be unique in the namespaceCan’t include whitespaceCan’t end with an underscoreCan’t contain two consecutive underscoresCan’t contain a hyphen (dash) The only exception to the last rule is when separating the namespace from the componentname in markup. For example, if the component is in the example namespace and has thename myComponent, the folder name should be myComponent, but the markup tag shouldbe <example-my-component>. The hyphen character (-) is required by the HTML standardfor custom element names. The other options are either invalid or not recommended. Forexample, including whitespace or using consecutive underscores will cause errors, andusing a single underscore will look odd and may confuse developers consuming thecomponent.

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 newentries are written to the cart and previous entries are deleted from the cart. A taximplementation is an integration that calculates and applies tax rates and amounts to a cartor an order based on various factors, such as product type, price, quantity, location, andtax rules. A tax implementation can use either an external tax service provider or customApex 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. Theseentries represent the tax amounts and adjustments that are applied to the cart. Beforewriting new entries to the cart, the tax implementation deletes any existing entries with atype of Charge and a charge type of Tax from the cart. This ensures that the tax calculationis accurate and up-to-date based on the current state of the cart and avoids any conflicts orinconsistencies with previous tax entries. Previous entries are not copied to another objector modified with the new tax calculation, as these are not valid actions for handling existingtax entries.

Question # 64
When a developer configures a tax integration for a store, what happens to the previously calculated tax entries during the checkout flow?
A. Ignored during recalculation B. Saved prior to recalculation C. Deleted from the Cart D. Modified with the new tax calculation
Answer: C Explanation: When a developer configures a tax integration for a store, the previouslycalculated tax entries during the checkout flow are deleted from the Cart. A tax integrationis an integration that calculates and applies tax rates and amounts to a Cart or an Orderbased on various factors, such as product type, price, quantity, location, and tax rules. Atax integration can use either an external tax service provider or custom Apex code toperform the tax calculation. When a developer configures a tax integration for a store, anyexisting tax entries in the Cart are deleted before calling the tax integration service ormethod. This ensures that the tax calculation is accurate and up-to-date based on thecurrent state of the Cart and avoids any conflicts or inconsistencies with previous taxentries. The previously calculated tax entries are not ignored during recalculation, savedprior to recalculation, or modified with the new tax calculation, as these are not validactions for handling existing tax entries.

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
Answer: B Explanation: The Product Detail Card component is a standard component that displaysthe product information and options on the product page. It includes the followingelements1:The product’s SKUThe product’s unit of measureThe product’s available inventory, or a generic availability message, if specifiedThe product’s short descriptionThe product’s price informationThe product’s quantity selectorThe product’s add to cart buttonThe product’s image galleryTo replace this component with custom components, a developer can use the followingthree components:Product Fields Short component: This component displays the product’s shortdescription, SKU, unit of measure, and price information. It also allows thedeveloper to specify which fields to display and how to format them2.Product Field Long component: This component displays the product’s longdescription, which can include rich text and images. It also allows the developer tospecify which field to display and how to format it2.Product Detail Image Gallery component: This component displays the product’simage gallery, which can include multiple images and thumbnails. It also allows thedeveloper to specify the image field, the image size, and the image zoom option3.These three components can be combined to create a custom product page that shows theproduct information and options in a different layout and style than the out-of-the-boxProduct Detail Card component.

Question # 66
Which option is the correct syntax to render a property in a Lightning web component template?
A. Surround the property with curly braces: {property} B. Surround the property with brackets: [property] C. Surround the property with an exclamation point and curly braces: {property} D. Surround the property with curly braces and exclamation point: {{property}
Answer: A Explanation: The correct syntax to render a property in a Lightning web componenttemplate is to surround the property with curly braces: {property}. This syntax allows you to access the property value from the JavaScript class of the component and display it in theHTML template. The other options are incorrect because they either use invalid charactersor do not follow the standard syntax for rendering a property in a Lightning web componenttemplate.
