Cisco 350-601 topic 1 question 206

Refer to the exhibit. An engineer must configure FCoE between the N9K-A switch and the FCF-A Nexus 9000 core switch. The deployment has these characteristics:
✑ The N9K-A and N9K-B top-of-rack switches share the domain ID of the core switches.
✑ The hosts are equipped with converged network adapters.
✑ The only VSAN that is used is permitted to traverse port-channel 100 is VSAN 20.
Which configuration completes the FCoE configuration on the N9K-A device?

A.
N9K-A(config)# feature-set fcoe-npv N9K-A(config)# interface vfc-port-channel 100 N9K-A(config-if)# switchport mode E N9K-A(config-if)# switchport trunk allowed vsan 1, 20
B.
N9K-A(config)# feature-set fcoe-npv N9K-A(config)# interface vfc-port-channel 100 N9K-A(config-if)# switchport mode NP N9K-A(config-if)# switchport trunk allowed vsan 20
C.
N9K-A(config)# feature fcoe N9K-A(config)# feature npv N9K-A(config)# interface vfc 100 N9K-A(config-if)# bind interface port-channel 100 N9K-A(config-if)# switchport mode N N9K-A(config-if)# switchport trunk allowed vsan 1, 20
D.
N9K-A(config)# feature fcoe N9K-A(config)# feature npv N9K-A(config)# interface vfc 100 N9K-A(config-if)# bind interface port-channel 100 N9K-A(config-if)# switchport mode F N9K-A(config-if)# switchport trunk allowed vsan 20
