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 have converged network adapters.
  • The only VSAN 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
Explanation

An FCoE NPV edge switch connects upstream to an FCF core through an NP port; it must not use an E or F port for that core-facing link. Enabling feature-set fcoe-npv, configuring vfc-port-channel 100 as switchport mode NP, and allowing only VSAN 20 satisfies the required NPV uplink role and VSAN restriction.
