SK0-003 · Question #701
Which of the following stripes data at the bit level and uses a dedicated disk for parity?
The correct answer is B. RAID 3. RAID 3 stripes data at a bit or byte level across multiple drives and dedicates a single disk to store parity information, allowing for fault tolerance.

Why each option
RAID 3 stripes data at a bit or byte level across multiple drives and dedicates a single disk to store parity information, allowing for fault tolerance.
RAID 0 stripes data at the block level and does not provide any fault tolerance or parity.
RAID 3 is characterized by striping data at the byte or bit level across all data disks. It utilizes a single, dedicated disk to store parity information, which allows for data recovery in case of a single disk failure.
RAID 5 stripes data at the block level and distributes parity information across all disks, rather than using a dedicated parity disk.
RAID 10 combines RAID 1 (mirroring) and RAID 0 (striping), providing fault tolerance through mirroring but without using parity.
