Which dual-level RAID configuration is combined to configure RAID 10 on a single array?

Answer options

• A. RAID 0 RAID 1, mirrored and parity
• B. RAID 0 RAID 1, mirrored and striped
• C. RAID 1 RAID 0, parity and striped
• D. RAID 0 RAID 1, striped and mirrored

Correct answer: D

Explanation

The correct answer is D because RAID 10 is created by combining RAID 0 (striping for performance) with RAID 1 (mirroring for redundancy). The other options incorrectly describe the relationship between RAID 0 and RAID 1, either by mislabeling their functions or by combining them in a way that does not reflect how RAID 10 is structured.
