Cisco Video Infrastructure Implementation — Question 24

For Business to Business calls, which option must be configured on an Expressway Edge to route calls to an unknown domain?

Answer options

• A. traversal zone to a public DNS address
• B. neighbor zone to the other business
• C. SIP trunk to a public DNS server
• D. DNS zone and a public DNS address

Correct answer: A

Explanation

The correct answer is A, as a traversal zone to a public DNS address is essential for routing calls to domains that are not recognized. The other options do not provide the necessary configuration to handle calls for unknown domains, as they focus on local or specific connections rather than public DNS resolution.
