During an installation, you have selected two disks to be used for your ZFS root pool. What is the
impact?
A.
Only single disk configurations are supported for the root pool, so Solaris will use the current
boot disk for the root pool.
B.
Only single disk configurations are supported during the initial creation of a root pool. Mirrored
pools can only be created after the initial installation.
C.
A single ZFS volume will be used for the swap area and dump device.
D.
A mirrored two disk configuration is set up for the root pool.

“You can select the disk or disks to be used for your ZFS root pool. If you select two disks, a mirrored two-disk configuration is set up for your root pool. Either a two-disk or three-disk mirrored pool is optimal.”
