Show Suggested Answer Hide Answer
Suggested Answer: D

RAID 6 is a type of RAID that uses block-level striping with two parity blocks distributed across all member disks.It allows for two disk failures within the RAID set before any data is lost1.A minimum of four disks is requiredto create RAID 61. To increase the size of an existing RAID 6 array, the administrator can replace the array drives one at a time with larger drives and then expand the array.This way, the data and parity are rebuilt on each new drive and the array remains operational during the process2.
