CompTIA Cloud+ (CV0-004) — Question 15

Which of the following is a difference between a SAN and a NAS?

Answer options

• A. A SAN works only with fiber-based networks.
• B. A SAN works with any Ethernet-based network.
• C. A NAS uses a faster protocol than a SAN.
• D. A NAS uses a slower protocol than a SAN.

Correct answer: D

Explanation

The correct answer is D because a NAS typically uses protocols like NFS or SMB, which are generally slower than the block-level protocols used by a SAN, such as iSCSI or Fibre Channel. Options A and B incorrectly describe the network compatibility of SANs, while option C misstates the protocol speeds between NAS and SAN.
