Is it possible to change the encryption algorithm on a fully encrypted disk, without need to decrypt it first? Is it possible to re-encrypt the disk on-the-fly?

The correct answer is B. Changing the encryption algorithm is supported on all machines, but you must first decrypt it. Changing the encryption algorithm on a fully encrypted disk requires decrypting the disk first, changing the encryption algorithm, and then re- encrypting the disk with the new algorithm. This process ensures that the data is fully protected under the new encryption settings…

Explanation

Changing the encryption algorithm on a fully encrypted disk requires decrypting the disk first, changing the encryption algorithm, and then re- encrypting the disk with the new algorithm. This process ensures that the data is fully protected under the new encryption settings. Unfortunately, it's not possible to change the encryption algorithm on-the-fly without decrypting and re- encrypting the data.
