Topic #: 1
[All 1z0-821 Questions]

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?

  • A. The encrypted file system must have been created in Oracle Solaris11. To encrypt a ZFS file system from a previous version of Solaris, upgrade the zpool and create a new encrypted ZFS file system into the encrypted ZFS file system.
  • B. If you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 30.
  • C. ZFS encryption is integrated with the ZFS command set and no additional packages need to be installed.
  • D. ZFS encryption requires that the ZFS Dataset Encryption package be installed.
  • E. If you plan to create an encrypted file system in an existing zpool, the pool must be upgraded to ZFS version 21, minimum.
  • F. Encryption is supported at the pool or dataset (file system) level.
  • G. Encryption is supported at the pool level only for every file system in the pool will be encrypted.
  • H. You cannot create an encrypted file system in a zpool that was created prior to oracle Solaris11. Create a new zpool in Solaris11, create an encrypted ZFS file

Suggested Answer: ABCF 🗳️
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.
