NEW QUESTION # 50
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

A. Maintain all three triggers on the Expense __c object, but move the Apex logic out of the trigger definition.
B. Unity all three triggers In a single trigger on the Expense__c object that Includes all events.
C. Create helper classes to execute the appropriate logic when a record is saved.
D. Unify the before insert and before update triggers and use Flow for the delete action.

Answer: B,C

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.

NEW QUESTION # 51
A developer is asked to prevent anyone other than a user with Sales Manager profile from changing the Opportunity Status to Closed Lost if the lost reason is blank.
Which automation allows the developer to satisfy this requirement in the most efficient manner?

A. An error condition formula on a validation rule on Opportunity
B. approval process on the Opportunity object
C. A record trigger flow on the Opportunity object
D. An Apex trigger on the Opportunity object

Answer: A

Explanation:
An error condition formula on a validation rule on Opportunity is the automation that allows the developer to satisfy the requirement in the most efficient manner. A validation rule is a declarative feature that allows you to define criteria for data quality and integrity. It can prevent users from saving records that do not meet the specified conditions. In this case, the developer can create a validation rule on the Opportunity object that checks if the user profile is not Sales Manager, the Opportunity Status is Closed Lost, and the lost reason is blank. If these conditions are true, the validation rule can display an error message and prevent the record from being saved12.
