CompTIA Server+ (SK0-005) — Question 109

An administrator is installing a new file server that has four drive bays available. Which of the following RAID types would provide the MOST storage as well as disk redundancy?

Answer options

• A. RAID 0
• B. RAID 1
• C. RAID 5
• D. RAID 10

Correct answer: C

Explanation

RAID 5 provides a good balance between storage efficiency and redundancy, utilizing one disk for parity while allowing the remaining three disks to store data. RAID 0 offers no redundancy and uses all drives for storage, while RAID 1 duplicates data for redundancy at the cost of half the storage. RAID 10 offers redundancy and improved performance but uses half the total capacity for mirroring, making RAID 5 the most efficient option in this scenario.
