PD1 Process Automation & Logic 2

Question 1

A developer needs to prevent a Trigger from recursively firing. What is the recommended approach?

Accepted Answer

Use a static Boolean variable in a handler class to track if the trigger has already run

Answer

A static Boolean variable persists for the duration of a transaction, allowing triggers to check and set a flag to prevent re-entry.

Question 2

Which order of execution step occurs BEFORE Apex triggers fire on a record update?

Accepted Answer

System validation rules

Answer

Salesforce runs system validation rules before before-triggers in the order of execution.

Question 3

In a before-insert trigger, a developer sets a field value on Trigger.new records. What additional DML operation is required?

Accepted Answer

No additional DML; changes to Trigger.new are saved automatically

Answer

In before triggers, modifications to Trigger.new records are saved automatically without requiring a separate DML statement.

Question 4

A Flow built in Flow Builder needs to update a related Account when an Opportunity is closed. Which element should the developer use?

Accepted Answer

Get Records element followed by an Update Records element

Answer

A Get Records element retrieves the related Account, and an Update Records element applies changes to it.

Question 5

What does the `with sharing` keyword enforce in an Apex class?

Accepted Answer

Record-level sharing rules for the running user

Answer

`with sharing` enforces the running user's record-level sharing rules, preventing access to records they do not have permission to see.
