Refer to the exhibit.
Which two numbers match the regular expression? (Choose two.)
How do the Cisco Expressway-C and Expressway-E servers transmit media to each other?
An engineer is investigating failing incoming calls that are expected to connect. The engineer notices that the failed calls all have a port number of 5060 at the end of the URI. The search rules are configured in a way that they do not expect a port to be included. Which configuration allows the routing of this call?
Which DNS record and port combination must be resolved externally for Mobile and Remote Access to be used?
An engineer is deploying Mobile and Remote Access to allow external Cisco Jabber users to sign into a Cisco UCM cluster via Cisco Expressways. The users will sign-in in the format username@cisco.com. Contact photos for Jabber are hosted on a webserver with the FQDN of phonebook cisco.com. Which configuration must be completed to allow external Jabber users to see contact photos?
What are the steps to access the Service Setup Wizard during the first setup of the Expressway server to license the server?
Refer to the exhibit showing logs from the Expressway-C, a copy of the Expressway-E certificate, and the UC traversal zone configuration for the Expressway-C. An office administrator is deploying mobile and remote access and sees an issue with the UC traversal zone. The zone is showing “TLS negotiation failure”. What is causing this issue?
An Expressway pairs deployed for Mobile and Remote Access. An administrator installs a new server certificate on the Expressway-E. After installing the new certificate, the UC Traversal zone between Expressway-C and Expressway-E is active. Still, Jabber Mobile and Remote Access clients cannot log in over the Expressway. The certificate Common Name is the FQDN of Expressway-E, “expe01 example.com”, and the certificate contains no additional names. Which Subject Alternate Name must be added to the certificate to allow Jabber Mobile and Remote Access clients to log in successfully?
Which type of interface is required when the Cisco Expressway-E is located in a DMZ between two separate firewalls on separate network segments?
