3.多项选择题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.
