PDI Exam Dumps - Salesforce Developers Questions and Answers

The@TestVisibleannotation allows private methods or variables to be accessed in test classes. This ensures that the private method can be adequately tested without changing its access modifier.

A Global Picklist Value Set allows the same set of picklist values to be shared across multiple objects, making maintenance easier and ensuring consistency.

Why not other options?

B: Alphabetical ordering does not ensure consistent value maintenance across objects.

C: Validation rules do not streamline picklist value maintenance.

D: Restricting picklist values helps ensure data integrity but does not streamline maintenance across objects.

Global Picklists Documentation

Maximum Trigger Depth Exceeded:

This error occurs when a trigger causes recursive calls, leading to an infinite loop of execution.

Solution:

Use static variables in helper classes to prevent recursive trigger execution.

Example:

public class TriggerHelper {

public static Boolean isTriggerExecuted = false;

}

trigger AccountTrigger on Account (after update) {

if (!TriggerHelper.isTriggerExecuted) {

TriggerHelper.isTriggerExecuted = true;

// Trigger logic here

}

}

Why Not Other Options?

A: Permissions do not affect trigger recursion.

B: Length of the trigger is unrelated to recursion.

C: Code coverage does not influence runtime errors like recursion.

Scratch orgs are created using the Salesforce CLI (sfdx force:org:create) as part of Salesforce DX. It is specifically designed for development and testing purposes.

Why not other options?

B: Sandbox refresh is used for creating sandboxes, not scratch orgs.

C: Developer Console is used for debugging and code development but cannot create scratch orgs.

D: Workbench is a tool for API testing and data manipulation, not for scratch org creation.

Salesforce CLI and Scratch Orgs

Option C: Roll-up summary fields can cause triggers to fire again as they recalculate parent records.

Option D: After-save record-triggered flows can update records, which may fire triggers on those records.

Salesforce Triggers Documentation

Salesforce CLI allows developers to automate deployments and run unit tests as part of a continuous integration (CI) pipeline. It is the most efficient tool for scripting these processes.

Using a formula field is the most efficient solution to calculate the ratio between rejected and approved timesheets. It minimizes maintenance overhead by dynamically calculating the value based on the existing roll-up summary fields.

Example Formula:

Total_Rejected_Timesheets__c / Total_Approved_Timesheets__c

After running all tests, theOverall Code Coverage panelin the Developer Console shows the code coverage percentage for each class.

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

Checking Code Coverage

 Option B:Custom events in LWC allow data to be passed using thedetailproperty of theCustomEventobject. This is the recommended way to pass data in a custom event.

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.
