Which statement describes the status of this storage pool?

A.
It is a RAIDZ storage pool and can withstand a single disk failure; data will be striped at: disk
components.

B.
It is a double-parity RAIDZ storage pool and can withstand two disk failures; data will be striped
across four disk components.

C.
It is an improperly configured RAIDZ storage pool; data will be striped across four disk
components, but only three drives are protected with redundancy.

D.
It is an improperly configured RAIDZ storage pool; data will be striped across three disk
components, but only three drives are protected with redundancy.

Explanation:
Device c3t6d0 is not included in the RAIDZ storage pool. The other three devices
are included in the raidz pool. The data on these devices are protected.
Note: In addition to a mirrored storage pool configuration, ZFS provides a RAID-Z configuration
with either single, double, or triple parity fault tolerance. Single-parity RAID-Z (raidz or raidz1) is
similar to RAID-5. Double-parity RAID-Z (raidz2) is similar to RAID-6.
