A network engineer just informed Bob that the parity data for their RAID system has been corrupted. Which of the following best describes the output of this type of situation?

A.
The hot swappable drive has failed

B.
Data from other drives cannot be used to rebuild lost or corrupted data

C.
Three of the five drives cannot be reestablished

D.
The mean time to repair just decreased

Explanation:
Redundant array of inexpensive disks (RAID) provides fault tolerance
for hard drives and can improve system performance. Redundancy and speed are
provided by breaking up the data and writing it across several disks so different
disk heads can work simultaneously to retrieve the requested information. Control
data are also spread across each disk-this is called parity-so that if one disk
fails, the other disks can work together and restore its data.
