You want to create a ZFS file system with the following specifications:
lzjb compression enabled
Cannot consume more than 2 GB from the storage pool
Redundant data at the block level eliminated
Mounted as /data
Which command creates the desired file system?
A.
zfs create –o mountpoint=/data,compression=on,algorithm=lzjb,deduplication=on,quota=2g
/pool1/data
B.
zfs create –o mountpoint=/data compression=on algorithm=lzjb deduplication=on quota=2g
/pool1/data
C.
zfs create –o mountpoint=/data –o compression=on –o dedup=on –o quota=2g /pool1/data
D.
zfs create –o mountpoint=/data –o compression=on –o algorithm=lzjb –o deduplication=on –o
quota=2g /pool1/data
E.
zfs create pool/data zfs set mountpoint=/data,quota=2g, dedup=on,compression=on /pool1/data
Explanation:
Not on compression setting:
compression=on | off | lzjb | gzip | gzip-N
Controls the compression algorithm used for this dataset. The
“lzjb” compression algorithm is optimized for performance while
providing decent data compression. Setting compression to “on” uses
the “lzjb” compression algorithm.
Incorrect:Not A, Not E: Should not use commas like this.
Not B, Not D: There is no property algorithm named to this command. To specify the use of the
lzjb compression command we must use compression=lzjb.
