Flo is the administrator for a server that is using RAID 5 with a six-disk array. In this approach, what is the maximum number of disks that may fail without the permanent loss of data?
Correct Answer: C
In a RAID 5 array, all of the disks contain data except for the parity disk. Therefore, regardless of the number of disks in the array, only a single disk may fail before data is permanently lost.
