Salesforce PDI Exam Dumps - Actual Questions Answers

A: An External ID field is designed to store an ID from another external system, which can be used to match Salesforce records with data from an external source during data imports or integrations.

D: External ID fields are automatically indexed, which can significantly improve the performance of SOQL queries when filtering based on the External ID.

Why not other options?

B: External IDs cannot be formula fields. Only text, number, email, and auto-number fields can be set as External IDs.

C: While External IDs are useful for integrations, they do not make external data visible within Salesforce Mobile.

External IDs Overview

To ensure that the TestUtils class and its methods are only accessible by unit test methods, the class must be annotated with the @isTest annotation. This annotation limits the scope of the class and its methods to test contexts only.

Why @isTest?

Purpose of @isTest:

The @isTest annotation marks a class or method for use exclusively within test scenarios. It prevents the methods from being accidentally invoked in production code.

This ensures better test isolation and prevents misuse.

Static Test Data Methods:

Marking helper methods for test data creation as @isTest ensures they do not interfere with production code and are strictly for testing purposes.

Analysis of Options:

Option A: @isTest above line 03:

Incorrect. Applying @isTest only to the createAccount method would work, but the other methods in the class would still be accessible. This does not satisfy the requirement of restricting the entire class.

Option B: Add @isTest above line 01:

Correct. Annotating the class ensures all methods within the class are accessible only in the context of tests.

Option C: Change public to private on line 01:

Incorrect. Changing the class to private would cause a compilation error, as top-level classes in Salesforce cannot be declared private.

Option D: Remove static from line 03:

Incorrect. Removing static does not affect the test scope of the class or its methods. Static methods can still be invoked, and this does not restrict access to test contexts.

Correct Implementation:

The corrected code would look like this:

@isTest

public class TestUtils {

public static Account createAccount() {

Account acct = new Account();

// Set some fields on acct

return acct;

}

// Other methods...

}
