Why each option
This question asks to identify which protocols are encapsulated within Fibre Channel over Ethernet (FCoE).
iSCSI (Internet Small Computer System Interface) is a separate storage protocol that encapsulates SCSI commands over TCP/IP, not FCoE.
Fibre Channel over Ethernet (FCoE) is a storage protocol that encapsulates native Fibre Channel frames directly over Ethernet networks, allowing FC traffic to run on converged infrastructure.
CIFS (Common Internet File System) is a file-sharing protocol that operates over IP, distinct from Fibre Channel and FCoE.
DNSF is not a recognized standard storage or networking protocol.
SCSI (Small Computer System Interface) commands are the fundamental language used by Fibre Channel to communicate with storage devices, and since FCoE encapsulates Fibre Channel, it indirectly transports the SCSI commands carried within FC frames.
Concept tested: FCoE protocol encapsulation
