Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 174

An administrator is configuring an Intercluster Lookup Service between 10 Cisco UCM clusters. Due to security requirements, certificate-based authentication must be used. Due to the deployment size, the administrator wants to avoid manually exchanging certificates between the clusters. Which two steps must be followed to meet these requirements? (Choose two.)

Answer options

• A. Set all clusters to standalone on the ILS configuration page.
• B. Install multiserver CA-signed Tomcat certificates on all cluster publishers.
• C. Enable password-based authentication in conjunction with certificate-based authentication.
• D. Ensure that the cluster ID for all clusters is the same.
• E. Install multiserver CA-signed CallManager certificates on all cluster publishers.

Correct answer: B, C

Explanation

The correct answers are B and C. Installing multiserver CA-signed Tomcat certificates on all cluster publishers (B) is necessary for certificate-based authentication, while enabling password-based authentication in conjunction with it (C) provides an additional layer of security and simplifies the certificate exchange process. Options A, D, and E do not directly address the requirements of certificate-based authentication or the need to streamline certificate management.
