[All 300-820 Questions]

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-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.
  • B. 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.
  • C. 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.
  • D. 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.

The correct answer is: A. 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. In a typical deployment scenario, Expressway-C, located within the corporate network, establishes an outgoing connection to Expressway-E, which is deployed in the DMZ. Expressway-E acts as the edge device and facilitates communication with external endpoints. When an external endpoint initiates a call, Expressway-E receives the call and notifies Expressway-C about the incoming call, allowing for secure communication between internal and external endpoints.
