Oracle Exam 1Z0-821 Topic 3 Question 81 Discussion

Actual exam question for Oracle's 1Z0-821 exam

Question #: 81
Topic #: 3

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?

Azfs 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

BLoad 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

Czfs create pooll/dataLoad the Wednesday tape and enter:zfs recv -F pool1/data < /dev/rmt/0

DLoad the Sunday tape and enter:zfs recv pool1/data < /dev/rmt/0Load the Wednesday tape and enter:* commands missing*

Option B is the winner! I don't want to take any chances with my data. Restoring from the Sunday full backup and then applying the incremental backups is the safest approach.

I'm a bit confused about the missing commands in option D. Shouldn't the restore process be more complete? I'd go with option B to be on the safe side.

Let's go with option B then. It seems like the most thorough approach.

I think option B is the best bet too. It covers both Sunday and Wednesday backups.

Option D seems incomplete, I agree. Option B looks like a safer choice.

I think option A is the correct one because it mentions loading the Monday and Wednesday tapes to restore the data.
