What configuration is required when implementing FCoE?

A. disable LAN traffic on the interface

B. configure PortFast on the access port

C. permit all VLANs on the interface

D. permit all VSANs on the interface

Answer: A

Explanation: DCBX allows the switch to send a LAN Logical Link Status (LLS) message to a directly-connected CNA. Enter the shutdown lan command to send an LLS-Down message to the CNA. This command causes all VLANs on the interface that are not enabled for FCoE to be brought down. If a VLAN on the interface is enabled for FCoE, it continues to carry SAN traffic without any interruption.
