Dell EMC Associate – Information Storage and Management v4 — Question 109

In the event of a disk failure, which RAID level enables quick data reconstruction?

Answer options

• A. RAID 3
• B. RAID 5
• C. RAID 6
• D. RAID 10

Correct answer: D

Explanation

RAID 10 provides fast data reconstruction due to its combination of mirroring and striping, which allows for quick access to redundant data. Other RAID levels like RAID 5 and RAID 6, while they do offer redundancy, involve more complex calculations that can slow down the reconstruction process. RAID 3 does not have the same level of redundancy as RAID 10, making it less effective for quick recovery.
