• Question 121:

  What are three reasons that a developer should write Jest tests for Lightning web components? (Choose three)

  A. To test basic user interaction
  B. To verify that events fire when expected
  C. To test how multiple components work together
  D. To verify the DOM output of a component
  E. To test a component's non-public properties
  A. To test basic user interaction
  B. To verify that events fire when expected
  D. To verify the DOM output of a component

  Explanation

  Jest is a powerful JavaScript testing framework used for Lightning Web Components (LWC) to ensure individual units of code function correctly in isolation. One of the primary reasons to use Jest is to verify the DOM output of a component (Option D). Since LWC is a UI framework, Jest allows developers to inspect the rendered HTML to ensure that elements, classes, and data are displayed as intended after a state change. Furthermore, Jest is essential for testing basic user interaction (Option A) .

  Developers can simulate events like button clicks or text input and then assert that the component's state or UI updates accordingly.

  Another critical use case is to verify that events fire when expected (Option B) . Components often communicate with parents via custom events; Jest allows you to "spy" on these events to ensure they are dispatched with the correct detail payload at the right time. Conversely, Jest is not intended for testing how multiple components work together (Option C)--this is the domain of integration tests or end-to-end tests (like UTAM). Additionally, Jest tests should focus on the component's public API and observable behavior; testing non-public (private) properties (Option E) is generally discouraged as it leads to brittle tests that break upon internal refactoring. By focusing on DOM output, interactions, and events, Jest provides a fast, reliable way to maintain component quality.

• Question 122:

  A developer wants to create a Visualforce page that allows a user to search for a given account by Name. If the account is found, the account details should be populated on screen. If no account is found, an error message should be displayed to the user.

  How can this be accomplished? (Choose two.)

  A. Use the (apex: information) tag to display the error message
  B. Use the ApexPages.addMessage() method to add the error message
  C. Use the <apex:pageMessages> tag to display the error message
  D. Use the accountaddErrorQ method to add the error message
  B. Use the ApexPages.addMessage() method to add the error message
  C. Use the <apex:pageMessages> tag to display the error message

• Question 123:

  The Bulk API__________.

  A. Is based on REST principles and is optimized for loading or deleting large sets of data. You can use it to query, queryAII, insert, update, upsert, or delete many records asynchronously by submitting batches
  B. Provides a powerful, convenient, and simple REST-based web services interface for interacting with Salesforce. Its advantages include ease of integration and development, and it's an excellent choice of technology for use with mobile applications and web projects
  C. Is used to create, retrieve, update or delete records, such as accounts, leads, and custom objects, and allows you to maintain passwords, perform searches, and much more
  D. Is used to retrieve, deploy, create, update, or delete customizations for your org. The most common use is to migrate changes from a sandbox or testing org to your production environment
  A. Is based on REST principles and is optimized for loading or deleting large sets of data. You can use it to query, queryAII, insert, update, upsert, or delete many records asynchronously by submitting batches

• Question 124:

  A custom Visualforce controller calls the ApexPages.addMessage() method, but no messages are rendering on the page.

  Which component should be added to the Visualforce page to display the message?

  A. <apex:message for="info"/>
  B. <apex:facet name="messages" />
  C. <apex:pageMessage severity="info" />
  D. <apex:pageMessages />
  D. <apex:pageMessages />

• Question 125:

  Which type of controller is best suited when you want to add custom functionality to a standard controller page, or when you want reusable functionality throughout pages?

  A. Standard Controller
  B. Standard List/Set Controller
  C. Controller Extensions
  D. Custom Controller
  C. Controller Extensions

• Question 126:

  Universal containers needs to integrate with several external systems. The process is initiated when a record is created in Salesforce. The remote systems do not require Salesforce to wait for a response before continuing.

  What is the recommended best solution to accomplish this?

  A. Trigger with callout
  B. Platform event
  C. PushTopic event
  D. Outbound message
  D. Outbound message

• Question 127:

  Which statement is true about using ConnectApi namespace (also called Chatter in Apex)? (Choose two.)

  A. Chatter in Apex methods honor the 'with sharing' and 'without sharing' keywords
  B. Chatter in Apex operations are synchronous, and they occur immediately
  C. Chatter in Apex methods do not run in system mode; they run in the context of the current user
  D. Many test methods related to Chatter in Apex require the IsTest (SeeAIIData=true) annotation
  C. Chatter in Apex methods do not run in system mode; they run in the context of the current user
  D. Many test methods related to Chatter in Apex require the IsTest (SeeAIIData=true) annotation

• Question 128:

  Which method should be used to convert a Date to a String in the current user's locale?

  A. Date.format
  B. Date.parse
  C. String.format
  D. String. valueOf
  A. Date.format

  ---

  Explanation

  Handling date and time formatting across different countries is a common requirement in global Salesforce orgs. For example, a user in the US expects MM/DD/YYYY, while a user in the UK expects DD/MM/YYYY.

  The Date.format() method (Option A) is specifically designed to handle this localization automatically. When called on a Date instance, it converts the value into a String based on the locale settings of the logged. This is the most efficient and localized approach as it requires no manual mapping of date into a Date object. Option D (String.in user patterns.valueOf) returns a standard, non-localized format (YYYY-MM-DD), which is used for system logging or API payloads but is often confusing for end-users.

  Option C (String.format) is used for variable substitution within a string (e.g., "Hello {0}") and does not inherently handle date localization. By using the native .format() method, developers ensure a consistent and familiar user experience for employees worldwide.

• Question 129:

  Which two relationship queries use the proper syntax? (Choose Two)

  A. SELECT Name, (SELECT LastName FROM Contacts__r) FROM Account
  B. SELECT Name, (SELECT LastName FROM Contacts) FROM Account
  C. SELECT Id, Name, Account __r.Name FROM Contact WHERE Account r.Industry = 'Media'
  D. SELECT Id, Name, Account.Name FROM Contact WHERE Account.Industry = 'Media'
  B. SELECT Name, (SELECT LastName FROM Contacts) FROM Account
  D. SELECT Id, Name, Account.Name FROM Contact WHERE Account.Industry = 'Media'

• Question 130:

  Code must have X% overall code coverage.

  A. X= 100
  B. X = 75
  C. X = 65
  D. X = 50
  B. X = 75
