Dell Technologies Proven Professional – Information Storage and Management (2023) — Question 9

Which is a characteristic of RAID 6?

Answer options

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

Correct answer: A

Explanation

RAID 6 utilizes double parity, which allows it to withstand the failure of two disks simultaneously, providing enhanced data protection. In contrast, single parity (option B) is a feature of RAID 5, while options C and D do not apply to RAID 6 as it distributes parity information across multiple disks.
