Review the storage pool information: 

Which statement describes the status of this storage pool? 

Answer options:

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.

D

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.
