Salesforce Updated PDI Exam Questions and Answers by arjan

Comprehensive and Detailed Explanation From Exact Extract:

B (Correct):Apex methods exposed toFlowmust be:

Static

Annotated with @InvocableMethod

Accept aListof parameters (for bulkification)

Return aList of custom class objects

This method signature supports Flow Builder’s bulk processing model, which is required in enterprise scenarios where the Flow might process multiple records.

Why Prebuilt Components?

The Lightning Component Framework includes a library of prebuilt components, which developers can use to build applications faster.

Why Not Other Options?

A: The framework is exclusive to Lightning Experience, not Classic UI.

C: The framework does not provide templates but focuses on reusable components.

D: Extended governor limits are not provided by the framework.

The@AuraEnabled(cacheable=true)annotation makes an Apex method available to Lightning Web Components and allows it to be wired to a property while enabling client-side caching for improved performance.

Anonymous Apex allows developers to execute ad hoc code snippets without creating a permanent class or trigger. It is useful for tasks like bulk data manipulation or testing.

B. Deleting 15,000 inactive Accounts:

Anonymous Apex can perform ad hoc bulk operations to clean up data after a deployment.

Example:

Use Cases:List inactiveAccounts = [SELECT Id FROM Account WHERE IsActive__c = false LIMIT 15000];

delete inactiveAccounts;

C. Running a batch Apex class:

Anonymous Apex can execute batch jobs for data processing.

Example:

apex

Copy code

Database.executeBatch(new UpdateContactBatch());

A. Schedule an Apex class to run periodically: This requires a scheduled job, not Anonymous Apex.

D. Add unit test code coverage: Unit tests must be written in test classes and cannot be added using Anonymous Apex.
