LPIC-2 Exam 201 (Linux Engineer) — Question 8

What is the minimum number of disks required in a fully redundant RAID5 array?

Answer options

• A. 1
• B. 2
• C. 3
• D. 4
• E. 5

Correct answer: C

Explanation

A RAID5 array requires a minimum of three disks to achieve redundancy through parity. With fewer than three disks, it cannot provide the necessary error recovery and data protection that RAID5 is designed for. Therefore, options A and B are insufficient, while D and E exceed the minimum requirement.
