Exam DEA-1TT4 topic 1 question 74 discussion

D. FCoE ASIC

FCoE ASIC

D is correct: FCoE Overview  A protocol that transports FC data along with regular Ethernet traffic over a Converged Enhanced Ethernet (CEE) network  Uses FCoE protocol, defined by the T11 standards committee, that encapsulates FC frames into Ethernet frames  Ensures lossless transmission of FC traffic over Ethernet 1TT4 materiel

The answer should be C Fibre Channel Forwarder FCF handles FCoE login requests, applies zoning, and provides the fabric services typically associated with an FC switch. It also encapsulates the FC frames received from the FC port into the Ethernet frames and decapsulates the Ethernet frames received from the Ethernet Bridge to the FC frames.

Fibre Channel over Ethernet (FCoE) is a method of supporting converged Fibre Channel (FC) and Ethernet traffic on a data center bridging (DCB) network. FCoE encapsulates unmodified FC frames in Ethernet to transport the FC frames over a physical Ethernet network. Answer should be D

I believe it's actually B. See https://en.wikipedia.org/wiki/Fibre_Channel_over_Ethernet "FCoE encapsulation can be done in software with a conventional Ethernet network interface card, however FCoE CNAs offload (from the CPU) the low level frame processing and SCSI protocol functions traditionally performed by Fibre Channel host bus adapters."

CNA is : A physical adapter that provides functionality of both NIC and FC HBA  Encapsulates FC frames into Ethernet frames and forwards them over CEE links  Contains separate modules for 10 GE, FC, and FCoE ASICs

An FCoE switch has both Ethernet switch and FC switch functionalities. It has a Fibre Channel Forwarder (FCF), an Ethernet Bridge, and a set of ports that can be used for FC and Ethernet connectivity. FCF handles FCoE login requests, applies zoning, and provides the fabric services typically associated with an FC switch. It also encapsulates the FC frames received from the FC port into the Ethernet frames and decapsulates the Ethernet frames received from the Ethernet Bridge to the FC frames.

should it not be fcf

agree FCoE ASIC
