H. When the system is booted, execute the zpool replace pool1 c3t3d0 c3t3d0 command.

Correct Answer:C
You might need to replace a disk in the root pool for the following reasons: The root pool is too small and you want to replace it with a larger disk
The root pool disk is failing. In a non-redundant pool, if the disk is failing so that the system won't boot, you'll need to boot from an alternate media, such as a CD or the network, before you replace the root pool disk.
In a mirrored root pool configuration, you might be able to attempt a disk replacement without having to boot from alternate media. You can replace a failed disk by using the zpool replace command.
Some hardware requires that you offline and unconfigure a disk before attempting the zpool replace operation to replace a failed disk.
For example:
# zpool offline rpool c1t0d0s0
# cfgadm -c unconfigure c1::dsk/c1t0d0

# cfgadm -c configure c1::dsk/c1t0d0
# zpool replace rpool c1t0d0s0
# zpool online rpool c1t0d0s0
# zpool status rpool
