CompTIA Server+ (SK0-005) — Question 296

A new client has a two-drive NAS that shows 878 of capacity with 60% utilization. While troubleshooting an issue for the client, a technician notices the NFS folders are empty. Upon further investigation, the technician discovers the client changed the configuration from RAID 0 to RAID 1. Which of the following is the most likely reason for this issue?

Answer options

• A. Data corruption
• B. RAID card damage
• C. Media failure
• D. Array rebuild

Correct answer: D

Explanation

The most likely reason for the issue is the array rebuild, which occurs when changing from RAID 0 to RAID 1. During this transition, the data must be duplicated to ensure redundancy, which can temporarily result in empty folders. The other options, such as data corruption, RAID card damage, and media failure, are less relevant to the scenario of changing RAID configurations.
