CompTIA Network+ (N10-007) — Question 9

Which of the following storage network technologies inherently leverages block-level storage?

Answer options

• A. NAS
• B. SAN
• C. FCoE
• D. iSCSI
• E. FTP

Correct answer: B

Explanation

The correct answer is B, SAN, as it is specifically designed for block-level storage, allowing multiple servers to access shared storage devices. Options A (NAS) and E (FTP) are focused on file-level storage and data transfer, respectively, while C (FCoE) and D (iSCSI) are protocols that can transport block storage but do not inherently leverage it.
