Refer to the exhibit. What are "Type" field values for this Expressway servers zone configuration?

The correct answer is D. Expressway-C "Traversal client", Expressway-E "Traversal server". In a Cisco Expressway MRA or B2B traversal pair, the zone types reflect which side initiates and which side accepts the traversal connection through the firewall. The Expressway-C (inside the corporate network) acts as the Traversal Client - it initiates the connection outbound…

Explanation

In a Cisco Expressway MRA or B2B traversal pair, the zone types reflect which side initiates and which side accepts the traversal connection through the firewall. The Expressway-C (inside the corporate network) acts as the Traversal Client - it initiates the connection outbound through the firewall to the Expressway-E. The Expressway-E (in the DMZ or outside the firewall) acts as the Traversal Server - it listens for and accepts incoming traversal connections from the Expressway-C. This client/server pairing is fundamental to how firewall traversal works in the Expressway architecture. Options A, B, and C describe incorrect type pairings that would prevent the traversal zone from functioning.
