Which item represents the process that allows FCoE multihop using T11 standard FC-BB-5?

A.
distributed FCF

B.
FIP proxy

C.
N Port proxy

D.
FIP snooping

Explanation:
FIP snooping is used in multi-hop FCoE environments. FIP snooping is a frame inspection method
that can be used by FIP snooping capable DCB devices to monitor FIP frames and apply policies
based on the information in those frames. This allows for:
Enhanced FCoE security (Prevents FCoE MAC spoofing.)
Creates FC point-to-point links within the Ethernet LAN
Allows auto-configuration of ACLs based on name server information read in the FIP frames
