Choose 2 answers

Suggested Answer: A,D Vote an answer

Option A: Roll-up summary fields can cause the parent record to go through Save.
True.
When a child record changes, roll-up summary fields on the parent object are recalculated.
This causes the parent record to save, which can trigger triggers on the parent object.
Reference:
Option D: The trigger may fire multiple times during a transaction.
True.
Triggers can fire multiple times due to workflow updates, process builders, or roll-up summary field recalculations.
Developers should design triggers to handle potential recursion and multiple executions.
Option B: The validation rules will cause the trigger to fire again.
False.
Validation rules execute after triggers and do not cause triggers to fire again.
They validate the data before the final commit but do not initiate additional trigger executions.
Option C: Duplicate rules are executed once all DML operations commit to the database.
False.
Duplicate rules are evaluated after triggers but before the DML operations are committed.
They can prevent records from being saved but do not affect trigger execution after commit.
Conclusion:
The developer should consider options A and D while testing the trigger code, as they can impact trigger execution during transactions.
