The Ethernet interface must be configured as PortFast (use the spanning-tree port type edge trunk command).

Hi Martin,
Cia Martin, you’re saying the wrong thing. I agree with Fausto. Correct answer is B
Creating a Virtual Fibre Channel Interface
The Ethernet interface that you bind the virtual Fibre Channel interface to must be configured as follows:
•It must be a trunk port (use the switchport mode trunk command).
•The FCoE VLAN that corresponds to virtual Fibre Channel’s VSAN must be in the allowed VLAN list.
•FCoE VLAN must not be configured as the native VLAN of the trunk port.
•The Ethernet interface must be configured as PortFast (use the spanning-tree port type edge trunk command).
Instead, if you want to disable the vlan then:
Disabling LAN Traffic on an FCoE Link
You can disable LAN traffic on an FCoE link.
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.
