Which of the following RAID levels should be selected for a large capacity file server that requires MAXIMUM storage capacity and a reasonable degree of robustness?
The correct answer is C. RAID 5. For a large capacity file server requiring maximum storage capacity and reasonable robustness, RAID 5 is the optimal choice as it balances capacity utilization and data protection.

Why each option
For a large capacity file server requiring maximum storage capacity and reasonable robustness, RAID 5 is the optimal choice as it balances capacity utilization and data protection.
RAID 0 offers no data redundancy, meaning any single drive failure results in complete data loss, making it unsuitable for robustness.
RAID 1 mirrors data, providing excellent redundancy but only 50% storage capacity utilization, which is inefficient for maximum capacity.
RAID 5 stripes data across multiple disks and distributes parity information, allowing it to withstand a single drive failure while utilizing N-1 disk capacity, which is efficient for large storage needs.
RAID 10 combines striping and mirroring, offering high performance and redundancy, but like RAID 1, it only utilizes 50% of the raw disk capacity.
