To use TLS authentication between clusters, you must exchange Tomcat certificates between the publisher node of each cluster in the ILS network. https://community.cisco.com/t5/collaboration-blogs/cucm-intercluster-lookup-service-ils-configuration-guide-based/ba-p/3358335#PassAuth

Selected Answer: C
The correct answer is: The Tomcat certificate from Cluster B must be the Publisher. When configuring ILS with TLS Certificates, the Tomcat certificate from the Publisher cluster must be used on the Subscriber cluster. This is because the Publisher cluster is responsible for authenticating the Subscriber cluster. If the Tomcat certificate from the Subscriber cluster is used on the Publisher cluster, the connection will fail. The other options are incorrect because: The password is not used when configuring ILS with TLS Certificates. Cluster IDs do not need to be unique. The CallManager certificate is not used for ILS authentication. To resolve the issue, the engineer needs to exchange the Tomcat certificate from Cluster A with the Tomcat certificate from Cluster B.
