Dell EMC Associate – Information Storage and Management v5 — Question 84

Which is a characteristic of RAID 6?

Answer options

• A. All parity stored on a single disk
• B. Double parity
• C. Single parity
• D. Parity not used

Correct answer: B

Explanation

RAID 6 is unique because it uses double parity, allowing for two disk failures without data loss, which is not provided by the other options. Option A is incorrect as RAID 6 distributes parity across multiple disks, not just one. Options C and D misrepresent the parity mechanisms, as RAID 6 specifically employs double parity for redundancy.
