NEW QUESTION # 244

B. Expressway Control is the traversal server installed in the DMZ
C. The Expressway-E must be put in a firewall DMZ segment
D. It is possible to NAT both Expressway-E interfaces

NEW QUESTION # 245
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 by using secure SIP. Which two configurations are the cause of the issue? (Choose two.)

A. The Tomcat certificate has the incorrect FQDN for the Cisco UCM server.
B. The Jabber client cannot connect to its associated phone device by using Cisco Computer Telephony Integration.
C. The incorrect secure device profile was applied to the Jabber client.
D. The Call Manager certificate is causing a conflict.
E. The Expressway-C does not allow two self-signed certificates with the same CN to be trusted.

Answer: D,E

Explanation:
Cisco Expressway-C does not support two self-signed certificates with the same Common Name (CN). Since both the CallManager and Tomcat certificates use the same CN and are self-signed, this creates a trust issue, especially with TLS verify mode enabled.
The CallManager certificate conflict arises because Expressway-C cannot differentiate between two certificates with the same CN when verifying TLS, causing secure SIP registration to fail.
To resolve this, use certificate authority (CA)-signed certificates with unique CNs for each service or use different FQDNs per certificate.

NEW QUESTION # 246

NEW QUESTION # 247
Cisco media traversal technology has enabled a secure environment where internal video endpoints call and receive calls from external video endpoints.
How does the Expressway-C and Expressway-E communicate?

A. Expressway-E establishes an outgoing request to Expressway-C, enabling the Expressway-C in the DMZ to notify the internal Expressway-E of an incoming call from an external endpoint.
B. Internal endpoints are registered to Expressway-C in the DMZ. Expressway-E, which is also in the DMZ, will receive and make calls on behalf of Expressway-C because they are in the same network.
C. Internal endpoints are registered to Expressway-E in the DMZ. Expressway-C, which is also in the DMZ, will receive and make calls on behalf of Expressway-E because they are in the same network.
D. Expressway-C establishes an outgoing request to Expressway-E, enabling the Expressway-E in the DMZ to notify the internal Expressway-C of an incoming call from an external endpoint.
