Accepted Answer

C

Explanation: Test.startTest() and Test.stopTest() should wrap the method call for resource allocation. Test.setMock() sets a mock callout for the test to handle callouts. Reference: Apex Developer Guide - Testing HTTP Callouts

Question 2

Refer to the test method below: https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/PDII/page_47_img_1.jpg The test method calls an @future method that increments the Number_of_Times_Viewed__c value. The assertion is failing because the Number of Times Viewed_c equals 0. What is the optimal way to fix this?

Accepted Answer

C

Explanation: When a test method calls an @future method that performs DML operations, the changes made by the @future method won't be visible until after the Test.stopTest() is called. This method ensures that all asynchronous processes are completed before the test execution continues. Therefore, Test.startTest() should be before the call to the @future method and Test.stopTest() immediately after. Reference: Apex Developer Guide - Testing Asynchronous Apex

Question 3

Accepted Answer

A, B, E

Explanation: 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. Reference: Visualforce Guide

Question 4

A user receives the generic "An internal server error has occurred” while interacting with a custom Lightning component. What should the developer do to ensure a more meaningful message?

Accepted Answer

D

Explanation: Use AuraHandledException in try-catch for custom errors. It enables sending meaningful, user- friendly error messages to the Lightning component. Reference: Handling Errors in Lightning Components

Question 5

A developer is asked to develop a new AppFxchange application. A feature of the program creates
Survey records when a Case reaches a certain stage and is of a certain Record Type. This feature
needs to be configurable, as different Salesforce instances require Surveys at different times.
Additionally, the out-of-the-box AppExchange app needs to come with a set of best practice settings
that apply to
most customers.
What should the developer use to store and package the custom configuration settings for the app?

Accepted Answer

C

Explanation: Custom metadata is best for storing configurable settings. It's deployable, packageable, and upgradeable. Allows different configurations for different instances. Reference: Custom Metadata Types

Question 6

Consider the controller code below that is called from an Aura component and
returns data wrapped in a class.
PDII practice exam questions

The developer verified that the queries return a single record each and there is error handling in the
Aura component, but the component is not getting anything back when calling the controller
getSemeData.
‘What is wrong?

Accepted Answer

D

Explanation: For the data to be passed back to the Aura component, all properties of the Apex class that are intended to be accessed from the component need to be annotated with @AuraEnabled. Without this annotation, the Aura framework cannot serialize the properties to send them to the front end. Reference: Aura Components Developer Guide - AuraEnabled Annotation

Question 7

Universal Containers implements a private sharing model for the Convention Attendee co custom
object. As part of a new quality assurance effort, the company created an Event_Reviewer_c user
lookup field on the object.
Management wants the event reviewer to automatically gain ReadWrite access to
every record they are assigned to.
What is the best approach to ensure the assigned reviewer obtains Read/Write access to the record?

Accepted Answer

B

Explanation: Use Apex Managed Sharing with an after insert trigger. It allows dynamic record sharing based on user-defined criteria like the Event_Reviewer_c field. Reference: Apex Managed Sharing

Question 8

Universal Containers develops a Visualforce page that requires the inclusion of external JavaScript
and C55 files. They want to ensure efficient loading and caching of the page.
Which feature should be utilized to achieve this goal?

Accepted Answer

C

Explanation: Static resources are ideal for efficient loading and caching of external files in Visualforce. They allow bundling and minimizing HTTP requests. Reference: Using Static Resources

Question 9

Question 10

A company has a Lightning page with many Lightning Components, some that cache reference dat
a. It is reported that the page does not always show the most current reference data.
What can a developer use to analyze and diagnose the problem in the Lightning page?

Accepted Answer

D

This is useful for diagnosing issues related to stale or outdated cache data that may prevent the most current reference data from displaying. Reference: Salesforce Lightning Inspector Chrome Extension

Question 11

Salesforce users consistently receive a "Maximum trigger depth exceeded” error when saving an Account. How can a developer fix this error?

Accepted Answer

D

Explanation: A common solution to the "Maximum trigger depth exceeded” error is to use a static variable in a helper class. The variable acts as a switch to ensure the trigger logic only executes once per transaction, preventing recursive trigger calls. Reference: Salesforce Developer Blog - Avoiding Recursive Trigger Calls

Question 12

A developer is creating a Lightning web component to display a calendar. The component will be
used in multiple countries. In some locales, the first day of the week is a Monday, or a Saturday, or a
Sunday. ‘What should the developer do to ensure the calendar displays accurately for users in every
locale?

Accepted Answer

B

Explanation: Use the @salesforce/i18n module with the firstDayOfWeek property. It provides locale-aware functionality essential for internationalization. Reference: Internationalization with Lightning Web Components

Question 13

A developer is working on an integration between Salestorce and an external system. The integration
requires sending a large amount of data to the external systern, which can cause long response times
and timeouts.
To optimize the performance and avoid timeouts, which technique should be used?

Accepted Answer

B

Explanation: Implementing an asynchronous callout using the Continuation class is the optimal solution to handle long response times and avoid timeouts in Salesforce. It allows the Apex code to make a long- running request to an external service and free up the thread to serve other requests. Reference: Apex Developer Guide - Asynchronous Callouts

Question 14

Recently, users notice that fields that were recently added for one department suddenly disappear without warning. Which two statements are true regarding these issues and resolution? Choose 2 answers

Accepted Answer

A, C

Explanation: Using a dedicated sandbox for testing before deployment can prevent issues like overwriting changes in production. When administrators deploy their own change sets without coordination, they might inadvertently overwrite each other's changes, including page layouts. Reference: Best Practices for Deployments with Change Sets

Question 15

A developer built an Aura component for guests to self-register upon arrival at a front desk kiosk.
Now the developer needs to create a component for the utility tray to alert users whenever a guest
arrives at the front desk.
What should be used?

Accepted Answer

C

Explanation: Application Events in Aura components are used for communication between components that are not in the same containment hierarchy. An application event to alert users about the arrival of a guest at the front desk is appropriate because it allows any component within the app to listen and respond to the event, regardless of where it is located in the component hierarchy.
