200-155 · Question #7

Which two protocols are encapsulated in FCoE? (Choose two.)

The correct answer is B. Fibre Channel E. SCSI. FCoE (Fibre Channel over Ethernet) is a networking protocol that encapsulates Fibre Channel frames directly over Ethernet networks, carrying SCSI commands within those frames.

Why each option

FCoE (Fibre Channel over Ethernet) is a networking protocol that encapsulates Fibre Channel frames directly over Ethernet networks, carrying SCSI commands within those frames.

AiSCSI

iSCSI is a distinct storage protocol that encapsulates SCSI commands over TCP/IP, making it an alternative to FCoE, not a protocol encapsulated within it.

BFibre ChannelCorrect

Fibre Channel is the primary protocol that FCoE is designed to transport, enabling traditional Fibre Channel traffic to operate over standard Ethernet infrastructure.

CCIFS

CIFS (Common Internet File System) is a network file-sharing protocol operating at a higher layer in the networking stack and is unrelated to FCoE encapsulation.

DDNSF

DNSF (Domain Name System Firewall) is not a recognized protocol involved in storage encapsulation or FCoE architecture.

ESCSICorrect

SCSI (Small Computer System Interface) commands are the fundamental data payload carried within Fibre Channel frames, making SCSI indirectly encapsulated when Fibre Channel is encapsulated in FCoE.
