A customer is configuring an upstream disjoint Layer 2 network in a Cisco UCS domain. So far
they have configured the following:
Fabric Interconnects are in switching mode.
There is symmetrical configuration for high availability.
There are no overlapping VLANs.
Each vNIC is communicating with one disjoint Layer 2 network.
After validating the above, the customer is still having issues with network connectivity. What
is the issue?

A.
Overlapping VLANs are allowed in a disjoint Layer 2 network.

B.
The vNIC configuration is incorrect and must communicate with two or more disjoint layer 2
networks.

C.
The fabric interconnect must be in end-host mode for a disjoint Layer 2 network.

D.
Asymmetrical configuration for high availability needs to be configured.
