What is a characteristic of the NFS protocol?

The correct answer is A. It uses remote procedure calls with TCP/IP for transport. NFS (Network File System) is a distributed file system protocol that uses Remote Procedure Calls (RPC) as its foundation, with TCP/IP as the transport layer (NFSv4 mandates TCP). Option B is incorrect because Cisco UCS B-Series servers boot via PXE or SAN, not NFS. Option C is…

Explanation

NFS (Network File System) is a distributed file system protocol that uses Remote Procedure Calls (RPC) as its foundation, with TCP/IP as the transport layer (NFSv4 mandates TCP). Option B is incorrect because Cisco UCS B-Series servers boot via PXE or SAN, not NFS. Option C is incorrect because NFS operates at the file level (not block level); iSCSI or FC are block-level protocols. Option D is incorrect because while early NFS versions used UDP, modern NFS (v3 and v4) primarily uses TCP, and HTTP is not an NFS transport mechanism.
