Which communication method does NFS use for requests between servers and clients?
Correct Answer: A
NFS uses XDR (External Data Representation) as the communication method for requests between servers and clients. XDR is a standard format for encoding and decoding data that is exchanged between different systems. XDR allows NFS to handle data with different byte orders, word sizes, and data types. XDR is also used by ONC RPC, which is the underlying protocol for NFS. XDR ensures that the data is represented consistently and correctly across different platforms and architectures. References :=
