Explanation

Deploying both Expressway-C (inside the network) and Expressway-E (in the DMZ) together provides two primary capabilities: (A) Secure firewall traversal - the paired architecture allows SIP and media traffic to traverse firewalls without opening inbound firewall ports, using a secure traversal zone; and (C) VPN-less remote access - remote workers can register their endpoints and access full collaboration features (voice, video, messaging) without needing a VPN client, because Expressway-E acts as the secure public-facing entry point. Options B, D, and E describe monitoring and visibility features that are not core Expressway-C/E functions.
