To enable secure video communication with external partners and customers while ensuring security for the deployment and connectivity, the best option would be: C. Cisco Expressway-C and Cisco Expressway-E Cisco Expressway-C and Cisco Expressway-E together form the Cisco Expressway Series. They provide secure communication for remote and external users to connect with the internal Unified Communications Manager securely. Expressway-C is deployed inside the corporate network, while Expressway-E is deployed in the DMZ (Demilitarized Zone) to provide secure access for external users. This setup allows for secure traversal of firewalls and NAT (Network Address Translation) devices, ensuring both connectivity and security for external video communication.
