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.

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.

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 < Account > 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.

Comprehensive and Detailed Explanation From Exact Extract:

A (Correct):The renderAs= " application/pdf " attribute in the < apex:page > tag instructs the Visualforce page to render the content as a PDF file when accessed.

Example:

< apex:page renderAs= " application/pdf " >

< h1 > Invoice < /h1 >

< /apex:page >

Incorrect options:

B:renderAs= " pdf " is incorrect; the correct MIME type is application/pdf.

C/D:contentType controls headers but doesn ' t render the content as PDF.

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.

75% Code Coverage (A):To deploy Apex code to production, Salesforce requires at least 75% of the code to be covered by tests across the organization.

Comprehensive and Detailed Explanation From Exact Extract:

A (Correct):AnApproval Processcan lock a record (making it read-only) once the record meets certain criteria like stage = Closed/Won.

B (Correct):AValidation Rulecan prevent users from saving changes when the stage is Closed/Won, by throwing an error.

Example validation formula:

text

CopyEdit

AND(ISCHANGED(StageName), ISPICKVAL(StageName, " Closed Won " ))

Incorrect options:

C:Before triggers run before the record is saved but don’t prevent UI-level edits unless combined with DML rollbacks or errors.

D:Auto-response rules are for sending emails, not restricting edits.
