Which of the following RAID (Redundant Array of Independent Disks) levels uses disk striping and a dedicated parity drive?

A.
RAID-0

B.
RAID-1

C.
RAID-3

D.
RAID-5

Explanation:
RAID-3 uses striping and parity on a dedicated drive to provide fault tolerance.
Incorrect
Answers:
A: RAID-0 is not a fault tolerance system. It uses striping on all disks to improve performance but does not use parity to provide fault tolerance.
B: RAID-1 is a disk fault tolerance system in which two disks are exact mirrors of each other. Should the one disk fail, the system would still be operable, the failed disk can be replaced, and the mirror rebuilt.
D: RAID-5 uses striping and parity drive to provide fault tolerance.
