Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 480

What is a characteristic of the NFS protocol?

Answer options

• A. It uses remote procedure calls with TCP/IP for transport.
• B. It is used for booting Cisco UCS B-Series servers.
• C. It is used to access a storage array at a block level.
• D. It uses UDP and HTTP as its transport.

Correct answer: A

Explanation

The correct answer is A because NFS indeed uses remote procedure calls (RPC) over TCP/IP to facilitate file sharing across networks. Option B is incorrect as NFS is not specifically for booting Cisco UCS B-Series servers. Option C is wrong because NFS provides file-level access, not block-level access, and option D is incorrect since NFS typically uses TCP rather than UDP for reliable transport.
