Correct Answer: AB
Explanation/Reference:
Explanation:
Host Interfaces (HIFs) on fabric extender connections to servers in a port channel are supported in the regular non-vPC fabric extender topology and both the fabric extender straight-through and fabric extender active-active (A-A) topologies.
Cisco NX-OS supports FCOE only on straight-through topologies. The following figure shows the two fabric extenders in a straight-through topology. Cisco NX-OS does not support FCoE over A-A fabric extender HIFs.
Host CNAs can be dually homed in A-A mode to fabric extender HIFs, and the fabric extender should be in straight-through mode.
Only vPCs are supported across the HIFs to host CNAs . Cisco NX-OS does not support downlink server vPCs to host CNAs and fabric extender vPCs in A-A mode together.
