The storage pool configuration on your server is:
You back up the /pool1/data file system, creating a snapshot and copying that snapshot to tape (/dev/rmt/0).
You perform a full backup on Sunday night and Incremental backups on Monday through Saturday night at
11:00 pm. Each incremental backup will copy only the data that has been modified since the Sunday backup
was started.On Thursday, at 10:00 am, you had a disk failure. You replaced the disk drive (c4t0d0). You created pool
(pool1) on that disk.
Which option would you select to restore the data in the /pool1/data file system?
A.
zfs create pool1/dataLoad the Monday tape and enter:zfs recv pool1/data < /dev/rmt/0Load the Wednesday
tape and enter:zfs recv –F pool1/data < /dev/rmt/0
B.
Load the Sunday tape and restore the Sunday snapshot:zfs recv pooll/data < /dev/rmt/0zfs rollback pool1/
data@monLoad the Wednesday tape and restore the Wednesday snapshot:zfs recv –i pooll/data < /dev/
rmt/0zfs rollback pool1/data@wed
C.
zfs create pooll/dataLoad the Wednesday tape and enter:zfs recv -F pool1/data < /dev/rmt/0
D.
Load the Sunday tape and enter:zfs recv pool1/data < /dev/rmt/0Load the Wednesday tape and enter:*

Explanation:
First the full backup must be restored. This would be the Sunday backup.
Then the last incremental backup must be restored. This would be the Wednesday backup.
Before restoring the Wednesday incremental file system snapshot, the most recent snapshot must first be
rolled back.
By exclusion D) would be best answer even though it is incomplete.
