On localSYS, your SPARC based server, you back up the root file system with recursive snapshots of the root
pool. The snapshots are stored on a remote NTS file system.
This information describes the remote system where the snapshots are stored:
Remote system name: backupSYS
File system whore the snapshots are stored: /backups/localSYS
Mounted file system on localSYS: /rpool/snaps
Most recent backup name: rpool-1202
Disk c0t0d0 has failed in your root pool and has been replaced. The disk has already been part< and labeled
and now you need to restore the root file system. Which procedure would you follow to restore the ZFS root file
system on localSYS?

A.
boot cdrom -smount -f nfs backup_server:/rpool/snaps /rmtzpool create rpool c0t0d0s0cat /mnt/rpool.1202 |
zfs receive -Fdu rpoolzpool set bootfs=rpool/ROOT/solaris rpoolRecreate swap and dump devices.Reinstall
the bootblock on c0t0d0.

B.

Explanation:
How to Recreate a ZFS Root Pool and Restore Root Pool Snapshots
In this scenario, assume the following conditions:* ZFS root pool cannot be recovered
* ZFS root pool snapshots are stored on a remote system and are shared over NFS
* The system is booted from an equivalent Solaris release to the root pool version so that the Solaris release
and the pool version match. Otherwise, you will need to add the -o version=version-number property option and
value when you recreate the root pool in step 4 below.
All steps below are performed on the local system.
1.
Boot from CD/DVD or the network.
On a SPARC based system, select one of the following boot methods:
ok boot net -s
ok boot cdrom -s
If you don’t use -s option, you’ll need to exit the installation program.
2.
Mount the remote snapshot dataset.
For example:
# mount -F nfs remote-system:/rpool/snaps /mnt
3.
Recreate the root pool.
For example:
# zpool create -f -o failmode=continue -R /a -m legacy -o cachefile=/etc/zfs/zpool.cache rpool c1t0d0s0
4.
Restore the root pool snapshots.
This step might take some time. For example:
# cat /mnt/rpool.0311 | zfs receive -Fdu rpool
Using the -u option means that the restored archive is not mounted when the zfs receive operation completes.
5.
Set the bootfs property on the root pool BE.
For example:
# zpool set bootfs=rpool/ROOT/osolBE rpool
6.
Install the boot blocks on the new disk.
On a SPARC based system:
# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c1t0d0s0
