SK0-003 · Question #702

Which of the following stripes data at the block level and does not have a dedicated disk for parity?

The correct answer is D. RAID 0 and RAID 5. RAID 0 stripes data at the block level with no parity, while RAID 5 also stripes at the block level but distributes parity information across all disks, eliminating the need for a dedicated parity drive.

Why each option

RAID 0 stripes data at the block level with no parity, while RAID 5 also stripes at the block level but distributes parity information across all disks, eliminating the need for a dedicated parity drive.

ARAID 1 and RAID 5

RAID 1 uses mirroring, not striping. While RAID 5 fits the criteria, the combination is incorrect.

BRAID 2 and RAID 10

RAID 2 uses bit-level striping and dedicated disks for error correction codes (ECC), not block-level striping for data. RAID 10 uses striping over mirrors, which is block-level, but relies on mirroring for redundancy rather than parity.

CRAID 3 and RAID 0

RAID 3 uses byte-level striping and has a dedicated parity disk, which contradicts the condition of not having a dedicated disk for parity.

DRAID 0 and RAID 5Correct

RAID 0 performs block-level striping without any parity or redundancy, thus not using a dedicated parity disk. RAID 5 also uses block-level striping but distributes the parity information across all member disks, meaning there is no single dedicated parity disk.
