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

Option B seems the most logical choice. It involves restoring the full Sunday backup and then applying the incremental backups up to Wednesday. This way, we can ensure the data is fully recovered.
