CompTIA Security+ (SY0-501) — Question 656

A network administrator is trying to provide the most resilient hard drive configuration in a server. With five hard drives, which of the following is the MOST fault- tolerant configuration?

Answer options

Correct answer: C

Explanation

RAID 6 is the most fault-tolerant option because it can survive the failure of two hard drives simultaneously, allowing for greater data protection. RAID 1 mirrors data but only provides redundancy for a single drive failure, while RAID 5 can only tolerate one drive failure. RAID 10, though resilient, requires a minimum of four drives and does not provide as much parity as RAID 6.
