CompTIA Server+ (SK0-005) — Question 231

A systems administrator needs to create a data volume out of four disks with the most redundancy. Which of the following is the best solution?

Answer options

• A. RAID 0
• B. RAID 1
• C. RAID 5
• D. RAID 6

Correct answer: B

Explanation

RAID 1 provides the highest level of redundancy by mirroring data across multiple disks, ensuring that if one disk fails, the data remains intact on another. RAID 0 offers no redundancy, RAID 5 requires a minimum of three disks but can only tolerate one disk failure, and RAID 6, while it offers more fault tolerance than RAID 5, does not provide as much redundancy as RAID 1 with only four disks.
