Declarative customizations, such as workflows, process builder, validation rules, and flows, offer a no-code approach to customizing Salesforce. Below are the key benefits:

Declarative customizations automatically update with each Salesforce release (A):Salesforce ensures that declarative tools are automatically updated during new releases, eliminating the need for manual intervention or code refactoring.

Database.insert(records, false):

The Database.insert() method with the allOrNone parameter set to false allows for partial success.

If some records in the list fail due to validation rules, triggers, or other errors, the method will still attempt to insert the remaining valid records.

The false parameter ensures that records that fail will not roll back the transaction for the others.

Why not the other options?

A. Database.insert(records, true):

The true parameter makes the operation transactional (all or none). If any record fails, all records will roll back.

B. insert records:

The insert DML statement behaves like Database.insert(records, true) by default and rolls back all records if any error occurs.

C. insert(records, false):

This syntax is invalid in Apex.

 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.

Order of Execution Rules:

Step 1: Original record is loaded from the database.

Step 2: Field-level validations are performed, including maximum field lengths.

Step 3: Old values are overwritten with new record values.

Step 4: JavaScript validation runs in the browser.

Salesforce requires that every trigger must have at least 1% test coverage to be deployed. Since the trigger in question has 0% test coverage, the deployment will fail even if the helper method and related classes meet the coverage requirement.

Using aforloop allows iterating through the list, and aniforif-elsecondition inside can evaluate theLastModifiedDatefor each account to determine its status.

Apex Control Statements

Event Propagation Phases in Aura Framework:

Default Phase: The framework executes handlers withevent.setDefault().

Bubble Phase: The event propagates upward from the target component to the root component.

Why Not Other Options?

A. Control: Not a valid Aura event propagation phase.

D. Emit: This is part of event creation, not propagation.

An Apex REST class can be used to retrieve real-time data from an external order management system. The flow can then call the REST class to display the retrieved data on the screen dynamically.

Why Quick Actions?

Quick Actions allow developers to create prepopulated forms for creating or updating records.

They are a modern alternative to JavaScript buttons in Lightning Experience.

Why Not Other Options?

A: Validation rules enforce data integrity but do not create records.

B: Apex triggers automate processes but are not used for user-initiated actions.

C: Record-triggered flows execute automatically when records are created or updated, but they do not replace JavaScript buttons for user-initiated actions.

The Apex Interactive Debugger allows developers to step through code execution in real time, which is the most effective way to identify the root cause of the duplication issue.
