300-820 Exam Question 21

An engineer configures a Cisco Collaboration environment to use Mobile and Remote Access for external access for company users. The engineer uses OAuth with refresh on the Cisco UCM SIP lines for extra security and improved user experience. During the setup, Mobile and Remote Access does not work, it is enabled on the Cisco UCM and Cisco Expressways. SIP trunks on ports 5090 and 5091 are configured to avoid conflicts with other SIP trunks between internal Cisco UCM clusters. The traversal zone also uses port 6500. The traversal zone between Expressways shows no errors, and the requests hit Expressway-E from the Internet. What is the reason that the solution does not work?

A.The default port for Mobile and Remote Access is 6001. Therefore, the traversal port must be port
6001 for Mobile and Remote Access to work.

B.The default port for Mobile and Remote Access is 6500, which creates a conflict with the existing traversal zone port.

C.Mobile and Remote Access does not support OAuth with refresh with this configuration,

D.The default port for Mobile and Remote Access is 5091, which creates a conflict with the existing SIP trunks.
