Refer to the exhibit. An engineer configures FCoE in a newly installed data center. Which configuration must be applied to activate VSAN 100 on VFC 100?

In Fibre Channel over Ethernet (FCoE), VSANs are activated on VFC interfaces by mapping them to specific FCoE VLANs. This mapping allows FCoE frames carrying Fibre Channel traffic for a particular VSAN to be encapsulated within a designated Ethernet VLAN on the underlying physical Ethernet interface, making the VSAN operational on the VFC.

Allowing a VSAN on an Ethernet interface is part of configuring a trunk, but the direct activation on a VFC for FCoE requires the VLAN-to-VSAN mapping.

Issuing a 'shutdown lan' command on a VFC interface would administratively disable the LAN component of the FCoE interface, preventing traffic flow, not activating a VSAN.

While a VLAN is involved in FCoE, simply configuring 'a VLAN' on a VFC 100 interface is insufficient; the specific action required is to explicitly map an FCoE VLAN to the VSAN.
