Question 1

Which type of Flow is triggered automatically when a record is created or updated without any user interaction?

Accepted Answer

Record-Triggered Flow

Answer

A Record-Triggered Flow fires automatically based on create or update events on a specific object, without user interaction.

Question 2

What happens when an unhandled exception occurs in an Apex after-insert trigger?

Accepted Answer

The entire transaction, including the original DML that fired the trigger, is rolled back

Answer

An unhandled exception rolls back the entire transaction, including the original record insert that fired the trigger.

Question 3

A developer uses `System.enqueueJob()` to add a Queueable Apex job. What is the maximum number of Queueable jobs that can be chained in a single transaction in production?

Accepted Answer

1

Answer

Only one Queueable job can be enqueued per transaction in production; chaining allows each job to enqueue exactly one more.

Question 4

Which SOQL clause should a developer use to prevent row-lock contention during record updates in a high-volume trigger?

Accepted Answer

FOR UPDATE

Answer

`FOR UPDATE` locks the queried rows to prevent other transactions from modifying them concurrently, reducing deadlock risk.

Question 5

In a Record-Triggered Flow running in Before-Save context, what is the key advantage over After-Save context?

Accepted Answer

It can update the triggering record without a separate DML statement, reducing governor limit consumption

Answer

Before-Save flows update the triggering record directly without an extra DML operation, unlike After-Save flows which require a separate update.
