CompTIA Server+ (SK0-004) — Question 31

A server administrator is configuring 10 web servers, each of which can contain up to four hard disks. To get the HIGHEST level of redundancy for these servers, the administrator should:

Answer options

• A. configure using four disks in a RAID 0 array
• B. configure using four disks in a RAID 5 array
• C. configure using four disks in a RAID 6 array
• D. configure using four disks in a RAID 10 array

Correct answer: C

Explanation

RAID 6 is the best choice for maximum redundancy because it provides dual parity, allowing for the failure of two disks without data loss. RAID 0 offers no redundancy, while RAID 5 only allows for one disk failure, and RAID 10 requires a minimum of four disks but is less effective in terms of redundancy compared to RAID 6.
