How is a controller and extension specified for a custom object named "Notice" on a Visualforce page? A.
A. Option A B. Option B C. Option C D. Option D
Answer: C Explanation:In Salesforce, a controller and extension for a custom object on a Visualforce page can bespecified using the <apex:page> tag. The standardController attribute is used to associatethe page with a standard or custom object, and the extensions attribute is used to specifyan Apex class that extends the functionality of the standard or custom controller. The codesnippet in option C, <apex:page standardController="Notice"extensions="myControllerExtension">, correctly demonstrates this by associating theVisualforce page with a custom object named “Notice” and specifying an extension named“myControllerExtension”. References: You can find more information about controllers andextensions in the Visualforce Developer Guide and the [Apex Developer Guide] onSalesforce’s official website.
Question # 12
Universal Containers wants to automatically assign new cases to the appropriate support representative based on the case origin. They have created a custom field on the Case object to store the support representative name. What is the best solution to assign the case to the appropriate support representative?
A. Use a trigger an the Case object. B. Use a formula field on the case object. C. Use a validation rule on the Case object. D. Use an Assignment Flow element.
Answer: D Explanation: An Assignment Flow element is a logic element that allows you to set valuesin variables, collection variables, record variables, record collection variables, and globalvariables1. You can use an Assignment Flow element to assign the support representativename to the custom field on the Case object based on the case origin. This way, you canautomate the case assignment process without writing any code or using any formula. Atrigger, a formula field, and a validation rule are not the best solutions for this scenario, asthey either require code, are not dynamic, or do not change the field value.

Question # 13
What are two considerations for deploying from a sandbox to production? Choose 2 answers
A. Should deploy during business hours to ensure feedback can be Quickly addressed B. All triggers must have at least one line of test coverage. C. At least 75% of Aptx code must be covered by unit tests. D. Unit tests must have calls to the System.assert method.
Answer: C,D Explanation: The correct answers are C and D because they are the minimumrequirements for deploying Apex code from a sandbox to production. According to theSalesforce documentation1, “To deploy Apex or package it for the AppExchange, at least75% of your Apex code must be covered by unit tests, and all of those tests must completesuccessfully.” Additionally, “Every test method must use the System.assert methods toverify that the expected behavior occurs.” The other options are incorrect because they arenot mandatory for deployment, but rather best practices or recommendations. Deployingduring business hours may not be feasible or desirable for some organizations, dependingon their availability and change management processes. Having at least one line of test coverage for each trigger is not enough to ensure code quality and functionality, and maynot meet the 75% code coverage requirement.

Question # 14
Universal Containers wants to ensure that all new leads created in the system have a valid email address. They have already created a validation rule to enforce this requirement, but want to add an additional layer of validation using automation. What would be the best solution for this requirement?
A. Submit a REST API Callojt with a JSON payload and validate the f elds on a third pattysystem B. Use an Approval Process to enforce tne completion of a valid email address using anoutbound message action. C. Use a before-save Apex trigger on the Lead object to validate the email address anddisplay an error message If it Is invalid D. Use a custom Lightning web component to make a callout to validate the fields on athird party system.
Answer: C Explanation: A before-save Apex trigger on the Lead object can validate the emailaddress using regular expressions or other logic and display an error message if it isinvalid. This solution is efficient, scalable, and does not require any external dependenciesor user intervention.

Question # 15
A Next Best Action strategy uses an Enhance element that invokes an Apex method to determine a discount level for a Contact, based on a number of factors. What is the correct definition of the Apex method?
A. Option A B. Option B C. Option C D. Option D
Answer: C Explanation:The correct definition of the Apex method is shown in option C. This Apex method isdefined as an invocable method, meaning it can be called from a process or flow. It’smarked with the @InvocableMethod annotation. The method returns a list of lists ofrecommendations and takes a list of ContactWrapper objects as input, which allows forbulk processing of records in flows.

Which three resources in an Aura component can contain JavaScript functions? Choose 3 answers
A. Renclerer B. Style C. Helper D. Controller E. Design
Answer: C,D,E Explanation: A helper is a JavaScript resource that contains functions that can be reusedby the component’s controller or other helpers. A controller is a JavaScript resource thatcontains functions that handle user interactions and events in the component. A renderer isa JavaScript resource that overrides the default rendering behavior of the component.A style is a CSS resource that defines the appearance of the component.

Question # 17
Given the following Apex statement:
What occurs when more than one Account is returned by the SOQL query?
A. The query falls and an error Is written to the debug log. B. The variable, nvAccount, Is automatically cast to the List data type. C. The first Account returned Is assigned to myAccour.t. D. An unhandled exception is thrown and the code terminates.
Answer: D Explanation: To create a form that will create a record for a custom object, the developercan use a Dynamic Form, which is a Lightning App Builder component that allows you tocustomize the fields and sections of a record page layout1. A Dynamic Form can also usevisibility rules to display different fields based on the user’s profile, role, or othercriteria2. To add the functionality to the Account record page, the developer can use aDynamic Action, which is a way to configure actions on a record page without code3. ADynamic Action can also use visibility rules to show or hide actions based on the user’sprofile, role, or other criteria4. To restrict the functionality to a small group of users, thedeveloper can create a Custom Permission, which is a way to grant access to customprocesses or apps5. A Custom Permission can be assigned to a permission set or a profile,and then assigned to the users who need it. References:Dynamic Forms | Salesforce TrailheadVisibility Rules for Dynamic Forms | Salesforce HelpDynamic Actions | Salesforce Trailhead Visibility Rules for Dynamic Actions | Salesforce HelpCustom Permissions | Salesforce Trailhead[Assign Custom Permissions | Salesforce Help]In Apex, if a SOQL query returns more than one row and the result is assigned to a singlesObject variable, an exception will be thrown. This is because a single sObject variable canonly hold one record. In this case, since myAccount is declared as a single Account object,it cannot hold more than one record. If the SOQL query returns more than one Account, anunhandled exception occurs, and the code terminates. References: The behavior can beunderstood from the Apex Developer Guide under the section of SOQL Queries
Question # 18
Which code displays the contents of a Visualforce page as a PDF?
A. <apenipage contentType="pdf"> B. <apex:page contentType=“application/pd£f"> C. <apexipage renderAs="pdf"> D. <apex:page renderAs="application/pdf">
Answer: C Explanation:You can render any page as a PDF by adding the renderAs attribute tothe <apex:page> component, and specifying "pdf" as the rendering service1. Forexample: <apex:page renderAs="pdf">. You can also usethe PageReference.getContentAsPDF() method in Apex to render a Visualforce page asPDF data, and then use Apex code to convert that PDF data to an email attachment, adocument, a Chatter post, and so on2.

Question # 19
Which code in a Visualforce page and/or controller might present a security vulnerability?
A. <apex:outputfield value="(!ctrl.userinput)" rendered="(!isfditable}" /> B. <apex:outputText escape="false" value="{!sCurrentPage.parameters.userInput}™ /> C. <apex:outputField value="{'ctrl.userInput}" /> D. <apex:outputText value="{!SCurrentPage.parameters.useriInput}" />
Answer: B Explanation:This code is vulnerable to a cross-site scripting (XSS) attack, because it takes usersuppliedinput and outputs it directly back to the user without escaping the XSS-vulnerablecharacters, such as <, >, ", ', and &. By setting the escape attribute to false, the developerdisables the anti-XSS filter that is enabled by default for most Visualforce tags. An attackercan exploit this vulnerability by injecting malicious HTML or JavaScript code into theuserInput parameter, which can then execute on the user’s browser and compromise theirsecurity or privacy.

Question # 20
In terms of the MVC paradigm, what are two advantages of implementing the view layer of a Salesforce application using Lightning Web Component-based development over Visualforce? Choose 2 answers
A. Log capturing via the Debug Logs Setup page B. Built-in standard and custom set controllers C. Self-contained and reusable units of an application D. Rich component ecosystem
Answer: C,D Explanation: The correct answers are option C and option D. Lightning Web Components are selfcontainedand reusable units of an application that follow web standards and can leveragemodern web features. They also benefit from a rich component ecosystem that includesstandard components, custom components, and third-party components. Visualforce, onthe other hand, is a legacy framework that relies on server-side rendering and proprietarymarkup. It does not offer the same level of modularity, performance, and interoperability asLightning Web Components. References: The information can be referenced from theofficial Salesforce documentation and learning materials available on Trailhead.Specifically, it aligns with the objectives outlined in Lightning Web Components Basics,where the benefits and features of Lightning Web Components are discussed.
