CompTIA A+ Core 1 (220-1001) — Question 106

A customer's workstation will not boot. A technician runs diagnostics on the system and discovers it is set up in a RAID 0 configuration, and a single SATA hard drive has failed. The system was set up for performance. Once repaired, the customer requests redundancy be built into the system and an increase in performance.
Which of the following describes how the technician should set up the new RAID configuration?

Answer options

• A. RAID 1 configuration that will utilize new SSD
• B. RAID 5 configuration that will allow the loss of a hard drive without failure
• C. RAID 6 configuration that will allow the loss of two hard drives without failure
• D. RAID 10 configuration utilizing new HDD

Correct answer: D

Explanation

RAID 10 combines the benefits of both RAID 0 and RAID 1, offering improved performance and redundancy by mirroring data across pairs of drives and striping. RAID 1 does not provide increased performance, RAID 5 and RAID 6 offer redundancy but with lower performance compared to RAID 10. Therefore, RAID 10 is the best choice to meet the customer's requirements for both enhanced performance and redundancy.
