Which three methods allow storage access across an IP network? (Choose three.)

FCIP (Fibre Channel over IP) encapsulates native Fibre Channel frames inside TCP/IP, enabling SAN-to-SAN connectivity across IP wide area networks. It is an IETF standard (RFC 3821) specifically designed to extend Fibre Channel storage traffic over existing IP infrastructure.

Fibre Channel over GRE is not a recognized or standardized storage networking protocol in any major standards body or vendor implementation.

Fibre Channel over L2TPv3 is not a recognized or standardized storage networking protocol.

iSCSI transports block-level SCSI storage commands over TCP/IP networks, allowing servers to access remote storage arrays using standard Ethernet and IP routing. It is an IETF standard (RFC 7143) widely deployed for IP-based storage area networking.

NFS (Network File System) is an IETF standard protocol (RFC 7530) that provides file-level storage access over IP networks using TCP or UDP. It enables clients to mount and access remote file systems transparently across IP infrastructure.
