Refer to the exhibit. A Cisco UCM cluster in mixed mode is integrated with Cisco Expressway-C for Mobile and Remote Access endpoint registration. TLS verify mode is enabled and self-signed certificates with the same common name for Cisco Tomcat and Cisco Call Manager are uploaded to Expressway-C. A Cisco Jabber client fails to register using secure SIP. Which two configurations are the cause of the issue? (Choose two.)

The Tomcat certificate has the incorrect FQDN for the Cisco UCM server.

The Jabber client cannot connect to its associated phone device by using Cisco Computer Telephony Integration.

The incorrect secure device profile was applied to the Jabber client.

The Expressway-C does not allow two self-signed certificates with the same CN to be trusted.

The Call Manager certificate is causing a conflict.
