Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 28

An engineer has two Cisco UCM clusters and wants them using ILS with TLS Certificates. Cluster A (Pub and 1 Subscriber) will be the hub, and Cluster B (Pub and 1 Subscriber) will be the spoke. Both clusters have self-signed certificates. The engineer has exchanged Publisher A and Subscriber B Tomcat certificates, but the connection fails. What is the cause of the failure?

Answer options

• A. The password is incorrect.
• B. Cluster IDs are not unique.
• C. The Tomcat certificate from Cluster B must be the Publisher.
• D. The engineer needs to exchange the CallManager certificate.

Correct answer: C

Explanation

The failure occurs because the Tomcat certificate from Cluster B should be the Publisher's certificate to establish a proper connection. The other options do not address the specific requirement for the certificate roles in the ILS configuration, making them incorrect in this context.
