To reduce the use at storage space on your server, you want to eliminate duplicate copies of data in your
server’s ZFS file systems. How do you specify that pool1/data should not contain duplicate data blocks on write
operations?
A.
zfs create –o compression=on pool1/data
B.
zpool create –o deduplication=on pool1 ; zfs create pool1/data
C.
zpool create –o dedupratio=on pool1 ; zfs create pool1/data
D.
zfs create –o dedupratio=2 pool1/data
E.
zfs create –o dedup=on pool1/data
Explanation:
To c reate a file system with deduplication:
root@solaris:~# zfs create -o dedup=on
Note: If you have a storage pool named ‘tank’ and you want to use dedup, just type this:
zfs set dedup=on tank
