An office administrator is deploying mobile and remote access and sees an issue with the UC traversal zone. The zone is showing ''TLS negotiation failure''. What is causing this issue?

AThe Expressway-E certificate includes the Expressway-C FQDN as a SAN entry

BThe Expressway-C is missing the FQDN of Cisco UCM in the Common Name of its certificate

CIn the UC Traversal Zone on the Expressway-C, the peer address is set to the IP of the Expressway-E,
which is not a SAN entry in the Expressway-E certificate

That's a good point. If the Expressway-E doesn't have the FQDN of Cisco UCM listed as a SAN in its certificate, that could also be the culprit.

Option C looks promising to me. The fact that the peer address in the UC Traversal Zone is set to the IP of the Expressway-E, which is not a SAN entry in the Expressway-E certificate, could definitely cause the TLS negotiation failure.

I agree, the key here is to figure out what the issue is with the TLS negotiation failure. Let's go through the options carefully.

Hmm, this question seems to be testing our understanding of certificate configuration and traversal zone setup. It's important to pay attention to the details like the SAN entries and the common name in the certificates.
