CompTIA Server+ (SK0-005) — Question 268

A storage administrator is configuring a new array to provide storage to a virtual cluster. The array has a built-in backup agent to allow data that is stored on the array to be backed up. The storage administrator wants the virtual cluster to use a file-based storage protocol so the backup agent can just back up the files that change and not the whole data store. Which of the following storage protocols should the administrator use?

Answer options

• A. iSCSI
• B. FC
• C. FCoE
• D. NFS

Correct answer: D

Explanation

The correct answer is D (NFS) because it is a file-based storage protocol that allows for efficient backup of only the changed files. Options A (iSCSI), B (FC), and C (FCoE) are block storage protocols, which do not support file-level backup capabilities as required by the administrator.
