Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cancel the key deletion from the KMS console or API.
When a KMS key is scheduled for deletion, the deletion can be canceled from the AWS KMS console or via the CancelKeyDeletion API during the pending deletion period. This immediate action restores the key to its previous state and prevents it from being deleted. Option B is incorrect because creating a new key does not cancel the deletion of the existing key. Option C is incorrect because deleted KMS keys cannot be restored; the default waiting period of 7–30 days exists specifically to allow cancellation. Option D is incorrect because disabling the key does not affect the deletion schedule.
