A customer has a 10GB volume with an 8GB LUN that is using 7GB. The snapshot policy is hourly and retains 48 snapshots. After a ransomware attack that encrypts all files on the LUN, the customer notices that all snapshots are gone.

D.
Autonomous Ransomware Protection
Suggested answer: A

Explanation:

The likely cause for the disappearance of all snapshots after a ransomware attack that encrypted all files on the LUN is the Snapshot autodelete feature. When the volume becomes full due to the encryption, the autodelete feature removes older snapshots to free up space, preventing the volume from running out of space and ensuring write operations can continue.
