Choose 3 answers

C<Apex:form>

Answer : A, B, E

and components can cause the form data to be sent to the server and can be configured to refresh specific parts of the page.

adds AJAX support to other components and can trigger partial page updates based on events such as onclick, onchange, etc.

Question 2

Which Salesforce feature allows a developer to see when a user last logged in to

Salesforce if real-time notification is not required?

ACalendar Events

BAsynchronous Data Capture Events

CEvent Monitoring Log

DDeveloper Log

Answer : C

Event Monitoring Log provides the ability to track different types of events in Salesforce, including user logins. These logs can be used to determine the last login time of a user without the need for real-time notification. Reference: Salesforce Help - Event Monitoring

Question 3

Consider the following code snippet:

A developer created the following test class to provide the proper code coverage for the snippet above:

However, when the test runs, no data is returned and the assertion fails.

Which edit should the developer make to ensure the test class runs successfully?

AImplement the without sharing keyword in the searchFeaturs Apex class.

BImplement the seeAllData=true attribute in the @1sTest annotation.

CEnclose the method call within Test. startbest i) and @Test_stopTast |).

DImplement the setFixedSearchResult= method in the test class.

Answer : D

To ensure that the test class for a search functionality in Salesforce runs successfully, the developer should use the Test.setFixedSearchResults() method. This allows the test to specify the records that are returned by the search, ensuring that the search behavior is predictable and that the assertion can be properly evaluated.

Question 4

Which interface needs to be implemented by an Aura component so that it may be displayed in modal dialog by clicking a button on a Lightning record page?

Afarce:lightningEditRAation

Blightning:editiction

Cforce:lightningQuickhction

Dlightning:quickAction

Answer : C

To display an Aura component in a modal dialog, the component must implement the force:lightningQuickAction or force:lightningQuickActionWithoutHeader interface. This allows it to be used as a quick action on record pages. Reference: Aura Components Developer Guide - Using Components in Quick Actions

Question 5

Which use case can be performed only by using asynchronous Apex?

AQuerying tens of thousands of records

BMaking a call to schedule a batch process to complete in the future

CCalling a web service from an Apex trigger

DUpdating a record after the completion of an insert

Answer : C

Making a callout from an Apex trigger is not allowed synchronously; hence, such callouts must be performed in an asynchronous context. The only way to perform this within the Salesforce platform is by using asynchronous Apex, such as @future methods or Queueable Apex. Reference: Apex Developer Guide - Asynchronous Apex

Question 6

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

Choose 3 answers

ATo test a component's non-public properties.

BTo test basic user interaction

CTo verify the DOM output of a component

DTo test how multiple components work together

ETo verify that events fire when expected

Answer : A, B, C

Jest tests are essential for developing Lightning Web Components (LWC) because they allow developers to ensure the quality and correctness of their components in isolation from the rest of the application. Reason A is incorrect because testing non-public properties breaks encapsulation and is considered bad practice. B is correct because Jest tests can simulate user interactions with the component, such as clicking buttons or entering text, to ensure it behaves as expected. C is correct as well because Jest tests can confirm that the component renders the expected DOM output, which is crucial for ensuring that the HTML structure of the component is accurate. D is not the best choice since Jest is more suited for testing components in isolation rather than how multiple components interact; integration tests are more appropriate for that. Lastly, E is correct because Jest tests can verify that events are fired at the appropriate times, which is a critical part of the component's interaction with the rest of the application.

Question 7

A Salesforce Platform Developer is leading a team that is tasked with deploying a

new application to production. The team has used source-driven development, and

they want to ensure that the application is deployed successfully.

What tool or mechanism should be used to verify that the deployment is successful?

AForce.com Migration Tool

BSalesforce DX CLI

CApex Test Execution

DSalesforce Inspector

Answer : B

The Salesforce CLI with Salesforce DX can be used to execute and verify the deployment of metadata to production. It allows the developer to run specified tests and ensure that the deployment meets all required conditions for success. Reference: Salesforce DX Developer Guide
