Which connection does the traversal zone configuration define?

The correct answer is C. Cisco Expressway-C and Cisco Expressway-E platforms. A traversal zone is the zone type specifically designed to establish a secure, firewall-traversing signaling and media connection between Expressway-C (the traversal client, inside the network) and Expressway-E (the traversal server, in the DMZ or outside). Expressway-C uses a…

Explanation

A traversal zone is the zone type specifically designed to establish a secure, firewall-traversing signaling and media connection between Expressway-C (the traversal client, inside the network) and Expressway-E (the traversal server, in the DMZ or outside). Expressway-C uses a 'Unified Communications traversal' zone to connect outbound to Expressway-E, which has a corresponding traversal server zone. This pair forms the core of the MRA and B2B architecture. The other options describe unrelated system pairings that do not use traversal zones.
