Which two protocols are used by the NFSv4 protocol? (Choose two.)
The correct answer is B. TCP E. IP. NFSv4 primarily uses the Transmission Control Protocol (TCP) for reliable data transfer and the Internet Protocol (IP) for network addressing and routing. These two protocols form the foundation of its network communication.

Why each option
NFSv4 primarily uses the Transmission Control Protocol (TCP) for reliable data transfer and the Internet Protocol (IP) for network addressing and routing. These two protocols form the foundation of its network communication.
FCP (Fibre Channel Protocol) is used for Fibre Channel networks, which is a different storage networking technology than NFS.
NFSv4, by default, exclusively uses TCP (Transmission Control Protocol) for all its operations, providing reliable, connection-oriented communication.
While older NFS versions (NFSv2, NFSv3) often used UDP, NFSv4 standardized on TCP for reliability and easier firewall traversal.
Ethernet is a Layer 2 technology that provides the physical and data link layer for IP, but IP and TCP are the direct protocols utilized by NFSv4, not Ethernet itself.
IP (Internet Protocol) is fundamental for network communication, providing addressing and routing capabilities for NFSv4 traffic across a network.
