With RAID Level 5 the spare drives that replace the failed drives are usually hot swappable, meaning
the can be replaced on the server while the?

A.
System is up and running.

B.
System is down and running.

C.
System is in-between and running.

D.
System is centre and running.

Explanation:
This is true, since RAID 5 uses parity to provide fault tolerance through the array, once of the disk in
it can become corrupted, and you usually can just take it out without turning off the system (Hot
SWAP) and plug a spare disk on the bay. Then the array will automatically begin to reconstruct the
information in the new disk with the parity contained through the other disks in the array. This Hot
Swap capability is usually present in enterprise servers that require high availability.
