You upgraded your server to Oracle Solaris 11 and you imported zpool (pool1) that was created in Solaris
10. You need to create an encrypted ZFS file system in pool1, but first you need to make sure that your server supports ZFS encryption.
Which four statements are true for support of ZFS encryption?
Correct Answer: A,B,C,F
Explanation/Reference:
A (not H): You can use your existing storage pools as long as they are upgraded. You have the flexibility of encrypting specific file systems.
B(not E): Can I enable encryption on an existing pool?
Yes, the pool must be upgraded to pool version 30 to allow encrypted ZFS file systems and volumes.
C(not D): ZFS encryption is integrated with the ZFS command set. Like other ZFS operations, encryption operations such as key changes and rekey are performed online.
F (not G): Encryption is the process in which data is encoded for privacy and a key is needed by the data owner to access the encoded data. You can set an encryption policy when a ZFS dataset is created, but the policy cannot be changed.
