We need to ensure that the certificates have the correct SAN entries for successful communication.

Definitely. It looks like a TLS negotiation failure due to mismatch in the certificates.

That makes sense. It's important for the SAN entries to match up in the certificates.

Yeah, I agree. The peer address set to the IP of the Expressway-E is not a SAN entry in the Expressway-E certificate.

I think the issue is with the UC Traversal Zone configuration on the Expressway-C.

Yeah, I'm with you guys. Although the other options seem plausible, C just seems to fit the problem description the best. Plus, it's always the little details that trip you up in these exams.

I agree, C does seem like the most likely culprit. The fact that the logs are showing a TLS negotiation failure suggests an issue with the certificate configuration.

Hmm, this seems like a tricky one. I'm not sure which answer is correct, but I'm leaning towards C. The issue with the UC traversal zone seems to be related to the peer address not matching the SAN entries in the Expressway-E certificate.
