Implementing Cisco Collaboration Cloud and Edge Infrastructure (CLCEI) — Question 47

Which two statements about Expressway media traversal are true? (Choose two.)

Answer options

• A. Expressway Control is the traversal server installed in the DMZ.
• B. The Expressway Edge must be put in a firewall DMZ segment.
• C. Cisco Unified Communications Manager zone can be either traversal server or client.
• D. The Unified Communications traversal zone can be used for Mobile and Remote Access.
• E. Both Expressway Edge interfaces can be NATed.

Correct answer: B, D

Explanation

Answer B is correct because the Expressway Edge is required to be in a firewall DMZ segment to facilitate secure communications. Answer D is also correct as the Unified Communications traversal zone supports Mobile and Remote Access capabilities. Answers A and C are incorrect as they misrepresent the roles of the components, and E, while technically true, is not relevant to the core functionality of the traversal zone.
