Oracle Exam 1Z0-580 Topic 2 Question 28 Discussion

A:

* Oracle Solaris 11 adds transparent data encryption functionality to ZFS. All data and file system metadata (such as ownership, access control lists, quota information, and so on) are encrypted when stored persistently in the ZFS pool.

* A very simple example of using ZFS encryption is as follows:

# zfs create -o encryption=on rpool/export/project

Enter passphrase for 'rpool/export/project':

Enter again:

# zfs create rpool/export/project/A

# zfs create rpool/export/project/A/design

# zfs create rpool/export/project/B

D: compression=on reduces storate footprint

E: If you want to allow the filesystem to be managed inside the zone, use the zfs zoned=on option when creating or modifying the filesystem.
