CompTIA A+ Core 1 (220-1001) — Question 19

A technician is configuring a new web server and must have over 10TB of fault-tolerant storage, while minimizing the number of failure points. The applications on the server also require the highest performance available. Which of the following configurations would the technician MOST likely select?

Answer options

• A. RAID 0 with 15000rpm 15TB drives
• B. RAID 1 with 10000rpm 8TB drives
• C. RAID 5 with 7200rpm 5TB drives
• D. RAID 10 with 5400rpm 6TB drives

Correct answer: D

Explanation

RAID 10 combines the benefits of both RAID 1 and RAID 0, offering fault tolerance and high performance, making it the best choice for this scenario. RAID 0 lacks redundancy, RAID 1 does not meet the storage requirement, and RAID 5, while providing fault tolerance, does not deliver the same level of performance as RAID 10.
