Which two type of endpoint are used for the Ethernet encapsulation of Fibre frames? (Choose two.)
The correct answer is C. Fibre Channel Forwarder (FCF) D. fCoE node (Enode). FCoE uses two endpoint types on the Ethernet fabric - the FCF switch on the network side and the Enode (fCoE node) on the host side.

Why each option
FCoE uses two endpoint types on the Ethernet fabric - the FCF switch on the network side and the Enode (fCoE node) on the host side.
FIP (FCoE Initialization Protocol) is a discovery and login protocol used to establish and maintain FCoE sessions, not an endpoint type involved in frame encapsulation.
Virtual Fibre Channel (vFC) is a logical interface configured on an FCF to connect toward an Enode or native FC device - it is an interface abstraction, not a standalone endpoint category.
A Fibre Channel Forwarder (FCF) is the FCoE-capable switch that terminates FCoE sessions on the Ethernet fabric side and forwards native FC frames toward the SAN, acting as the network-side endpoint responsible for bridging FCoE and native FC.
An fCoE Node (Enode) is a server or storage device equipped with a Converged Network Adapter (CNA) that encapsulates native Fibre Channel frames into Ethernet frames for transport across the FCoE fabric, making it the host-side endpoint.
iSCSI is a separate IP-based storage protocol that encapsulates SCSI commands over TCP/IP and has no role in the Ethernet encapsulation of Fibre Channel frames used by FCoE.
