Which of the following files contains details regarding the encryption state of an iTunes backup file?
A . Keychain-backup.plist
B . Manifest.mbdb
C . Manifest.plist
D . Status.plist

Answer: C

Explanation:

The Manifest.plist lists if the backup is encrypted. This will come into use and be required should the backup file need to be accessed forensically if it is locked. The Manifest.mbdb contains a listing of data stored in the backup. Even if the backup is encrypted, this data can be parsed for more information.
