A.
Client side attacks

B.
Clear text access

C.
Database theft

D.
Network-based attacks

Explanation:
Full-disk encryption encrypts the data on the device. This feature ensures that the data on the device cannot be accessed in a useable form should the device be
stolen.
Incorrect Answers:
A, D: Full-disk encryption encrypts the data on the device itself and ensures that the data on the device cannot be accessed in a useable form should the device be
stolen. It does not prevent client-side or network-based attacks.
C: Full-disk encryption encrypts the data on the device itself. It may help prevent access to database data but database encryption would be the preferred method
of protecting database data.
