Your company wants Server 1/eth0 （vNIC 1） configured so that it always uses Fabric Interconnect A Port Channel 1 （Po1） when it communicates with anything outside of the Cisco UCS domain. However， if vNIC 1 fails over to Fabric Interconnect B using fabric failover， then vNIC 1 can any uplink port on Fabric Interconnect B. Which statements are true？ （）

• A、 The fabric interconnects must be in end-host mode.
• B、 A pin group must be configured on the server tab in Cisco UCS Manager.
• C、 In the service profile for Server 1， vNIC 1 must be explicitly assigned to a pin group.
• D、 Server 1 cannot be configured to meet the requirement. A server can only be manually pinned to a single physical interface and not a port channel because of the LACP load-balancing algorithm.
• E、 Server 1 cannot be configured to meet the requirement. A server is either manually pinned to an uplink on both fabric interconnects or the server is automatically pinned， but not both.
