Answers
D.
Cryptographic erasure
Suggested answer: D

Explanation:

Cryptographic erasure is a secure method to destroy data by destroying the keys that were used to encrypt it. This method is universally available for volume storage on IaaS and is also extremely quick. Shredding, degaussing, and demagnetizing are all physically destructive methods that would not be permitted within a cloud environment using shared resources.
