CompTIA Server+ (SK0-005) — Question 264

A systems administrator is provisioning a SQL server with a RAID controller. The management team requires that the server be able to withstand at least a single hard drive failure, but the administrator is concerned that a computationally intensive RAID level may reduce server performance. Which of the following should the administrator choose?

Answer options

• A. RAID 0
• B. RAID 5
• C. RAID 10
• D. RAID 50
• E. RAID 60

Correct answer: C

Explanation

RAID 10 strikes a balance between redundancy and performance, allowing for one drive failure per mirrored pair while maintaining good read and write speeds. RAID 0 offers no redundancy, RAID 5 provides some fault tolerance but may have slower write speeds due to parity calculations, and RAID 50 and RAID 60 are more complex, possibly impacting performance further.
