Implementing Cisco Collaboration Applications (CLICA) — Question 52

Users on Cisco.com experience issues while using Cisco Jabber, and the error “Cannot communicate with the server” appears. An engineer checks the logs for the Jabber client and discovers the error LERR_JABBER_AUTH<17>: Authentication error with server e.g. resource bind. TLS, create a session or SASL error”. What should be checked to resolve this issue?

Answer options

• A. if the LDAP server is reachable and if port 5222 is open
• B. if the LDAP server is reachable and if port 443 is open
• C. if cup-xmpp certificates are valid and if port 8443 is open
• D. if the cup-xmpp certificates are valid and if port 5222 is open

Correct answer: D

Explanation

The correct answer is D because ensuring that the cup-xmpp certificates are valid is crucial for secure communication, and port 5222 is typically used for XMPP traffic. The other options either mention incorrect ports or do not address the validity of the necessary certificates for Jabber authentication.
