NEW QUESTION # 148
A developer identifies the following triggers on the Expense _c object:
The triggers process before delete, before insert, and before update events respectively.
Which two techniques should the developer implement to ensure trigger best practices are followed?
Choose 2 answers
Answer: B,D
Explanation:
A: Unify all three triggers in a single trigger on the Expense__c object that includes all events:
Salesforce best practices recommend having only one trigger per object to avoid redundancy and conflicts.
By combining all the events (before delete, before insert, and before update) into a single trigger, the developer can manage the logic in an organized and maintainable manner.
This also simplifies debugging and ensures that the trigger logic executes in a predictable order.
C: Create helper classes to execute the appropriate logic when a record is saved:
Using helper classes allows for a clean separation of concerns. The trigger becomes a dispatcher that delegates logic to dedicated classes.
For example, you can create methods like applyDefaultsToExpense(), validateExpenseUpdate(), and deleteExpense() in a helper class and invoke them from the trigger.
This improves reusability, readability, and testability of the code.
Why not the other options?
B: Unify the before insert and before update triggers and use Flow for the delete action:
While Flow is a powerful tool, it is not ideal for deleting records or replacing Apex trigger functionality, especially when triggers already exist for other events.
D: Maintain all three triggers on the Expense__c object but move the Apex logic out of the trigger definition:
Maintaining multiple triggers on the same object can lead to conflicts and execution order issues, even if the logic is moved to helper classes.
