CompTIA A+ Core 1 (220-1101) — Question 12

A technician is configuring a new CAD workstation that has four large hard drives. The workstation will be used to edit large, critical files, so the storage configuration should be both fast and redundant. Which of the following RAID levels BEST meets these requirements?

Answer options

• A. 0
• B. 1
• C. 5
• D. 10

Correct answer: D

Explanation

RAID 10 combines the benefits of both RAID 0 and RAID 1, offering both high speed and redundancy by mirroring and striping data. RAID 0 provides no redundancy, RAID 1 offers redundancy but lacks optimal performance, and RAID 5 provides some redundancy but with a performance hit during write operations, making RAID 10 the best choice for this scenario.
