A. B. C. D.C.
The correct answer is C. Cisco Expressway-C and Cisco Expressway-E.
Explanation: The Cisco Expressway-C and Cisco Expressway-E are designed for secure communication between internal and external entities, providing a secure traversal solution for audio, video, and data communications.
The Cisco Expressway-C is a traversal server that resides within the corporate network, and it acts as a proxy for all communications between the internal endpoints and the external network. It securely communicates with the Cisco Expressway-E to ensure that all external communication requests are authorized, encrypted, and secure. It also provides endpoint registration and call control services for the endpoints that are outside of the corporate network.
The Cisco Expressway-E is a traversal server that resides in the DMZ or outside of the corporate network, and it provides a secure link between external endpoints and the Cisco Expressway-C. It ensures that all communication requests are authorized and encrypted before allowing them into the corporate network. The Cisco Expressway-E also provides NAT and firewall traversal services, which are essential for secure external communications.
In summary, the Cisco Expressway-C and Cisco Expressway-E combination provides secure connectivity between internal and external endpoints, while also allowing the use of advanced collaboration features like video, audio, and data sharing. It also provides essential security services like encryption, NAT, and firewall traversal, ensuring that all communication requests are authorized and secure. Therefore, the correct answer is C. Cisco Expressway-C and Cisco Expressway-E.
