Salesforce PDI Exam Dumps - Valid Questions Answers

C. Update the PrimaryId__c field definition to mark it as an External Id:

Marking PrimaryId__c as an External Id allows Salesforce to use this field to match records during the data import process, streamlining the process of mapping CSV rows to existing Candidate__c records.

External Id fields are indexed and can be used in tools like Data Loader, Data Import Wizard, or API-based upserts to ensure that records are matched correctly based on the value of the external ID field.

In this case, since PrimaryId__c is unique, marking it as an external ID eliminates the need for custom triggers or flows.

Why this is the best solution?

This technique leverages built-in Salesforce capabilities (no need for custom code or automation).

It ensures accurate record matching and is the standard approach for data enrichment tasks involving unique identifiers.

Why not the other options?

A. Upload the CSV into a custom object related to Candidate__c:

This approach unnecessarily introduces another object, adding complexity. The goal is to update existing Candidate__c records, not store the data in a separate object.

B. Create a before insert trigger to correctly map the records:

Using triggers for this purpose is overengineering. Salesforce already provides tools like upsert for this exact use case. Writing a trigger would require additional effort and could introduce unintended errors or performance issues.

D. Create a before save flow to correctly map the records:

While flows are powerful, they are not the optimal solution for this use case. Data mapping is better handled using an external ID during import to ensure proper matching and updates.

Option A: The tag ensures that scripts are loaded only once, even if referenced multiple times.

Option D: The tag allows you to specify the order of scripts to ensure dependencies are loaded correctly.

Option E: Externally hosted scripts can be loaded using the scripts attribute.

Not Suitable:

Option B (Loading scripts in parallel): Scripts are loaded sequentially to ensure proper dependency handling.

Option C (Loading Files from Documents): Files must be hosted externally or in static resources, not in Documents.

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...

}
