Implementing Cisco Collaboration Cloud and Edge Infrastructure (CLCEI) — Question 25

Which zone is required on a B2B deployment between Expressway-C and Expressway-E?

Answer options

• A. traversal zone
• B. DNS zone
• C. default zone
• D. neighbor zone

Correct answer: A

Explanation

The traversal zone is essential for B2B deployments as it enables secure communication between Expressway-C and Expressway-E. The other zone types, such as DNS, default, and neighbor zones, do not facilitate the direct traversal of media and signaling, which is crucial for B2B interactions.
