Actual exam question from Cisco's 300-610

Question #: 186
Topic #: 1

Refer to the exhibit.

A Cisco engineer is configuring an active/active design that consists of Cisco Nexus 7000 Series Switches with Fabric Extenders using a vPC. The desired outcome is to allow the connection of servers/storage/devices to a single FEX, and use the FEX port channels to each parent switch to provide redundancy. The engineer configures FEX and FEX ID to be identical on both sides. During initial tests, an issue occurs with the straight-through FEX and active/active FEX configuration. What is the most probable reason?

A. They are not enabled on vPC+ deployments.
B. FEX-AA is not a supported F-Series module.
C. They cannot exist on the same ASIC instance.
D. Full duplex is disabled for FEX connectivity.

Selected Answer: C

C Guidelines and Limitations for FEX-AA The following are guidelines and limitations for FEX-AA: FEX-AA is not supported on vPC+ deployments. Before performing switchover manually, ensure the switch and fabric extenders are not undergoing any configuration change or hardware replacement. Configuring FEX-AA across two VDCs on the same chassis is not supported. FEXs configured in AA mode cannot have host interfaces configured in L3 mode. Straight-Through FEX and Active-Active FEX cannot exist on a same ASIC instance.
