CRT-450 Exam - Question 269

To prevent Opportunities from being editable when they reach the Closed/Won stage, a developer can implement a validation rule that restricts edits based on the stage. Validation rules are effective for enforcing conditions that must be met before a record can be saved. An automatically launched Approval Process can also be used, as it can change the record's status to a locked state once it enters the Closed/Won stage. A before-save Apex trigger is not appropriate in this scenario, as it runs before the record is saved and does not necessarily enforce the condition after the record is already in the Closed/Won stage. An auto-response rule is irrelevant in this context as it is used to send automatic email responses to cases or leads, not to control record editability.
