Implementing Cisco Collaboration Applications (CLICA) — Question 69

A collaboration engineer is troubleshooting an issue with Cisco Jabber for Windows clients. Users in a new branch location report that “cannot locate server” is displayed when they launch the client. When the engineer manually configures the server settings on a client, the client logs in successfully. The Cisco IM and Presence servers are located across the WAN at the corporate HQ. Which action resolves the issue?

Answer options

• A. Add a firewall rule to allow TCP/8443 from the branch to HQ.
• B. Add a _cisco-uds._tcp.company.com SRV record to the branch DNS server.
• C. Reinstall the Jabber clients with UPN_DISCOVERY_ENABLED=false.
• D. Add a _collab-edge._tls.company.com SRV record to the branch DNS server.

Correct answer: B

Explanation

The correct answer is B because adding a _cisco-uds._tcp.company.com SRV record to the branch DNS server enables the Cisco Jabber clients to locate the necessary Unified Domain Service for proper server discovery. The other options do not address the DNS resolution issue that is preventing the clients from finding the Cisco IM and Presence servers.
