Refer to the exhibit showing logs from the Expressway-C, a copy of the Expressway-E certificate, and the UC traversal zone configuration for the Expressway-C. 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?

• A.In 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
• B.The Expressway-E does not have the FQDN of Cisco UCM listed as a SAN in its certificate
• C.The Expressway-E certificate includes the Expressway-C FQDN as a SAN entry
• D.The Expressway-C is missing the FQDN of Cisco UCM in the Common Name of its certificate

Refer to the exhibit.

An Expressway-C and Expressway-E are configured for B2B calling and the Expressway- E zone is set to TLS Verify Currently, calls do not reach the Expressway-C. The Traversal Client zone on the Expressway-C for B2B reports the information in the exhibit for the Peer 1 address.
Which action resolves this error?

• A.Configure the Expressway-C Traversal Client zone transport protocol with TCP.
• B.Add an intermediate certificate to the Expressway-C that is signed by a certificate authority.
• C.Add a server certificate to the Expressway-C that is signed by a certificate authority.
• D.Configure the Expressway-C Traversal Client zone Peer 1 address with the fully qualified domain name of the Expressway-E.
