• Question 62:

  A developer created this Apex trigger that calls MyClass,myStartmethod:

  trigger my Trigger on Contact (before insert)

  [ MyClass.myStatilcMethed(trigger.new); ]

  The developer creates a test method that calls MyClase, myStartmethod directly, resulting in 81% overall code coverage.

  What happens wtier the developer tries to deploy the ... and two classes to production, assuming no other code exists?

  A. The deployment fails because the Apr- MgQM has no code coverage.
  B. The deployment tails because no assertions mett made in the lest method.
  C. The deployment passes became the Apex code has the requited 75% code coverage.
  D. The deployment passes because both classes and the trigger were included ki the deployment.
  A. The deployment fails because the Apr- MgQM has no code coverage.

• Question 63:

  Universal Containers decided to transition from Classic to Lightning Experience. They asked a developer to replace a JavaScript button that was being used to create records with prepopulated values.

  What can the developer use to accomplish this?

  A. Validation rules
  B. Apex triggers
  C. Record triggered flows
  D. Quick Actions
  D. Quick Actions

  ---

  Explanation

  Why Quick Actions?

  Quick Actions allow developers to create prepopulated forms for creating or updating records.

  They are a modern alternative to JavaScript buttons in Lightning Experience.

  Why Not Other Options?

  A: Validation rules enforce data integrity but do not create records.

  B: Apex triggers automate processes but are not used for user-initiated actions.

  C: Record-triggered flows execute automatically when records are created or updated, but they do not replace JavaScript buttons for user-initiated actions.

• Question 64:

  A developer is writing tests for a class and needs to insert records to validate functionality.

  Which annotation method should be used to create record for every method in the test class?

  A. @isTest (SeeAllData-true)
  B. @FreTest
  C. @TestSetup
  D. @StartTest
  C. @TestSetup

• Question 65:

  What is the value of the Trigger.old context variable in a before insert trigger?

  A. An empty list of sObjects
  B. Undefined
  C. null
  D. A list of newly created sObjects without IDs
  C. null

  ---

  Explanation

  Trigger.old in a before insert trigger:

  The Trigger.old context variable contains the old version of the records being processed in the trigger.

  In a before insert trigger, the records being processed are new and have no prior state in the database, so Trigger.old is null .

  This behavior is specific to insert triggers because there is no "old" record to reference before the record is created.

  Why is it null?

  The Trigger.old variable is only populated for triggers that handle updates or deletions (e.g., before update, after update, before delete, after delete). For insert operations, no previous state of the record exists.

  Why not the other options?

  A. An empty list of sObjects:

  This is incorrect because Trigger.old is not initialized as an empty list for insert triggers--it is simply null.

  B. Undefined:

  Trigger.old is defined in the trigger context, but it is null for insert operations. Undefined is not a valid Apex state.

  D. A list of newly created sObjects without IDs:

  This describes Trigger.new in a before insert trigger, not Trigger.old. Trigger.new contains the new records being inserted.

• Question 66:

  A team of developers is working on a source-driven project that allows them to work independently, with many different org configurations.

  Which type of Salesforce orgs should they use for their development?

  A. Developer sandboxes.
  B. Full Copy sandboxes
  C. Developer orgs
  D. Scratch orgs
  D. Scratch orgs

  ---

  Explanation

  Scratch orgs are temporary, source-driven Salesforce environments used for development and testing. They allow developers to:

  Work on independent features without interfering with each other's configurations.

  Utilize a source-driven development model for CI/CD pipelines.

• Question 67:

  What should a developer do to check the code coverage of a class after running all tests?

  A. View the code coverage percentage for the class using the Overall Code Coverage panel in the Developer Console Tests tab.
  B. View the Class Test Percentage tab on the Apex Class list view in Salesforce Setup.
  C. Select and run the class on the Apex Test Execution page in the Developer Console.
  D. View the Code Coverage column in the list view an the Apex Classes page.
  A. View the code coverage percentage for the class using the Overall Code Coverage panel in the Developer Console Tests tab.

  ---

  Explanation

  After running all tests, the Overall Code Coverage panel in the Developer Console shows the code coverage percentage for each class.

  This is the most reliable and optimal way to view code coverage.

• Question 68:

  Universal Containers decides to use exclusively declarative development to build out a new Salesforce application.

  Which three options should be used to build out the database layer for the application? Choose 3 answers

  A. Custom objects and fields
  B. Triggers
  C. Roll-up summaries
  D. Relationships
  E. Flows
  A. Custom objects and fields
  C. Roll-up summaries
  D. Relationships

  ---

  Explanation

  A: Custom objects and fields are the fundamental building blocks of the database layer in Salesforce for creating and storing custom data.

  C: Roll-up summary fields are a declarative feature used to perform calculations (e.g., sum, count) on child records and display the results on the parent record.

  D: Relationships (e.g., master-detail, lookup) are essential for defining how data objects are related to each other.

  Why not other options?

  B: Triggers are a programmatic solution, which goes against the declarative-only requirement.

  E: Flows are used for automation and logic, not for building the database layer.

• Question 69:

  A developer wrote an Apex method to update a list of Contacts and wants to make it available for use by Lightning web components.

  Which annotation should the developer add to the Apex method to achieve this?

  A. @AuraEnabled(cacheable-true)
  B. @AuraEnabled
  C. @RemoteAction
  D. @RemoteAction(cacheable-ture)
  B. @AuraEnabled

  Explanation

• Question 70:

  Universal Containers has a Visualforce page that displays a table of every Container__c being rented by a given Account. Recently this page is failing with a view state limit because some of the customers rent over 10,000 containers.

  What should a developer change about the Visualforce page to help with the page load errors?

  A. Implement pagination with an OffsetController.
  B. Implement pagination with a StandardSetController.
  C. Use JavaScript remoting with SOQL Offset.
  D. Use lazy loading and a transient List variable.
  B. Implement pagination with a StandardSetController.

  ---

  Explanation

  Pagination using a StandardSetController helps manage large datasets by loading only a subset of records at a time. This approach minimizes view state size, which is critical for handling large datasets like 10,000+ records.
