The ZFS configuration on your server is:
Pool1 6.67G31K/pool
Pool1/data31K31K/data
Select the three commands that you would use to 1. Create, 2. List, and 3. Delete a snapshot of
the /data file system.
A.
zfs snapshot pool1/data@now
B.
zfs create snapshot pool1/data@now
C.
zfs list -t snapshot
D.
zfs list -t snapshot pool1/data
E.
zfs destroy pool1/data@now
F.
zfs destroy snapshot pool1/data@now
Explanation:
A: Snapshots are created by using the zfs snapshot command, which takes as its
only argument the name of the snapshot to create.
D: You can list snapshots as follows:
# zfs list -t snapshot
E: Snapshots are destroyed by using the zfs destroy command. For example:
# zfs destroy tank/home/ahrens@now
AD
excuse ACE
Why not ADE? Its specifically asking for /data file system
ACE is right, as on the zfs list -t snapshot you cannot give the filesystem as parameter, only a snapshot itself. So D would be good if the command would be: zfs list -t snapshot pool1/data@now
B is incorrect as there is no zfs create snapshot. and so F is incorrect by the same reason.
root@sol11-ai:~# zfs snapshot rpool/tank@now
root@sol11-ai:~#
root@sol11-ai:~# zfs list -t snapshot rpool/tank
cannot open ‘rpool/tank’: operation not applicable to datasets of this type
root@sol11-ai:~# zfs list -t snapshot

man zfs:
-t type
A comma-separated list of types to display, where
type is one of filesystem, snapshot , volume, or
all. For example, specifying -t snapshot displays
only snapshots. The following aliases can be used in
place of the type specifiers: fs (filesystem), snap
(snapshot), and vol (volume).
