Implementing Cisco Collaboration Cloud and Edge Infrastructure (CLCEI) — Question 94

An administrator configures a secure SIP trunk in Cisco UCM to Expressway-C. The SIP trunk fails to become active, and an examination of a packet capture finds that the TLS handshake failed with a “Certificate Unknown” error from Cisco UCM. To allow the Cisco UCM to trust the Expressway-C and establish a TLS connection, the administrator will upload the Expressway server certificate to the trust store. To which trust store must the certificate be uploaded?

Answer options

Correct answer: B

Explanation

The correct trust store for uploading the Expressway server certificate is the CallManager-trust, as it is specifically used to manage trusted certificates for SIP trunks in Cisco UCM. The other options, such as tomcat-trust and ipsec-trust, serve different purposes and are not applicable for establishing trust with SIP trunks.
