Implementing Cisco Collaboration Cloud and Edge Infrastructure (CLCEI) — Question 28

A Jabber user is being prompted to trust the Expressway-E certificate when using Mobile and Remote Access. The administrator has validated that the
Expressway-E certificate is being trusted by the machine running the Jabber client.
What else can be done to solve this problem?

Answer options

• A. Create a new CSR with new information on the SAN field.
• B. Include Cisco Unified Communications Manager registration domain in the Expressway-E certificate as a SAN.
• C. Change the domain name.
• D. Change the FQDN of the Expressway.

Correct answer: B

Explanation

The correct answer is B because including the Cisco Unified Communications Manager registration domain in the Expressway-E certificate as a SAN (Subject Alternative Name) ensures that the Jabber client recognizes it as trusted. Options A, C, and D do not directly address the trust issue related to the certificate and may not resolve the underlying problem.
