4.多項選擇題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.

5.單項選擇題 Refer to the exhibit.

The Cisco UCS domain is operating in switching mode. A network administrator notices that no traffic is traversing the uplinks on Fabric Interconnect B （Path C）.

Which actions might be used to change this behavior？（）

A. Fix the port channel configuration between Fabric Interconnect B and Nexus 5548 B as the port channel IDs do not match.
B. Modify the bridge priority on the fabric interconnects so that one of the Nexus 5548s will always be the root bridge.
C. Modify the bridge priority on the Nexus 5548s so that one of them will always be the root bridge.
D. Modify the port priorities on the fabric interconnect uplinks （Paths B and C） so that they are a higher priority than ports Eth1/4 and Eth1/9 （Path D）.
E. This is an invalid configuration as Cisco UCS fabric interconnects cannot be directly connected.
