Oracle Exam 1Z0-820 Topic 4 Question 105 Discussion

Actual exam question for Oracle's 1Z0-820 exam

Question #: 105
Topic #: 4

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?

AThe 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.

BIf you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 30.

CZFS encryption is integrated with the ZFS command set and no additional packages need to be installed.

DZFS encryption requires that the ZFS Dataset Encryption package be installed.

EIf you plan to create an encrypted file system in an existing zpool, the pool must be upgraded to ZFS version 21, minimum.

FEncryption is supported at the pool or dataset (file system) level.

GEncryption is supported at the pool level only for every file system in the pool will be encrypted.

HYou 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 system in the new zpool, and move or copy the data from the existing file system into the new encrypted file system.

Seriously, why can't they just make encryption a simple one-click process? This is starting to sound like a job for a Solaris wizard. *waves magic wand*

Encryption at the pool level, huh? That's interesting. Though I suppose if every file system in the pool needs to be encrypted, it might as well be at the pool level. Gotta love ZFS and its flexibility!

Encryption at the pool level provides a convenient way to ensure all file systems are encrypted.

This is a bit confusing. So do I need to install the ZFS Dataset Encryption package or not? Guess I'll have to double-check the documentation to be sure.

Wait, so I can't encrypt a file system in a zpool created before Solaris 11? That's a bummer, guess I'll have to create a new zpool and migrate my data. At least the encryption is integrated into the ZFS command set.

Looks like I need to upgrade my zpool to version 30 before I can create an encrypted file system. That's good to know, thanks for the clear guidance!
