Salesforce Updated CRT-450 Exam Questions and Answers by wren

A try-catch block allows the batch to continue processing even if some records cause errors. Errors can be logged for review, ensuring the integration process does not stop entirely.

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.

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.

 Why Queueable?

Queueable Apex allows asynchronous processing, which can handle bulk updates efficiently without hitting governor limits.

The trigger enqueues the Queueable class to process the asset updates.

 Avoiding Limit Failures:

Moving logic to a Queueable class offloads resource-intensive operations to asynchronous processing.
