A. B. C. D.



Option B: classical Ethernet VLANs only, is the correct answer.

vPC+ or Virtual PortChannel+ is a feature on Cisco Nexus switches that allows two physical switches to appear as a single logical switch to the downstream devices. It helps in providing redundancy, load balancing, and scalability to the data center network.

In a vPC topology, both Nexus switches operate as one logical switch, and both the switches need to have the same configuration for the VLANs. The VLAN configuration is synchronized between the two switches, and the VLANs are allowed on the vPC port channel.

A vPC port channel is a logical interface that is created by bundling multiple physical links between two switches. The vPC port channel appears as a single interface to the downstream devices, and it provides higher bandwidth, redundancy, and load balancing.

Coming to the question, the type of VLANs that can be added to a trunk on a vPC port channel is classical Ethernet VLANs only. FabricPath VLANs are used to build a scalable and efficient Layer 2 network in the data center, but they cannot be sent over a vPC port channel. Similarly, native VLANs are used for untagged traffic, but they cannot be added to the vPC port channel.

In summary, the correct answer is B. classical Ethernet VLANs only.
