Implementing Cisco Collaboration Cloud and Edge Infrastructure (CLCEI) — Question 104

Which two considerations must be made when using Expressway media traversal? (Choose two.)

Answer options

• A. It is possible to NAT both Expressway-E interfaces
• B. The Unified Communications traversal zone should be used for MRA
• C. The Expressway-E must be put in a firewall DMZ segment
• D. Expressway Control is the traversal server installed in the DMZ
• E. Cisco UCM zone should be either traversal server or client

Correct answer: B, C

Explanation

The correct answers B and C highlight the necessary configurations for effective media traversal with Expressway. Specifically, using the Unified Communications traversal zone is essential for Mobile and Remote Access (MRA), and placing Expressway-E in a firewall DMZ is crucial for security. The other options, while related to Expressway, do not address the specific considerations for media traversal.
