Collaboration Communications Systems Engineer — Question 156

You have a Teams Phone deployment that has users in Canada and the United States.

You have a Session Border Controller (SBC) in Calgary and an SBC in New York City. Both SBCs are connected to Direct Routing.

You plan to implement toll bypass for the users in Canada. The solution must meet the following requirements:

• Prioritize the New York City SBC for calls to numbers in the United States.
• Leverage the Calgary SBC for resiliency if the New York City SBC is unavailable.

You create a PSTN usage named Canada and associate this policy to a voice routing policy.

Which two voice routes should you create with the Canada PSTN usage? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.

Answer options

• A. Create a wildcard voice route that has a priority of 2 and references the gateway in Calgary.
• B. For only United States numbers, create a voice route that has a priority of 2 and references the gateway in Calgary.
• C. Create a wildcard voice route that has a priority of 1 and references the gateway in New York City.
• D. For only United States numbers, create a voice route that has a priority of 1 and references the gateway in New York City.

Correct answer: A, D

Explanation

The correct answer includes option A because it provides a fallback route to the Calgary SBC with a lower priority when required. Option D is correct as it prioritizes calls to the United States through the New York City SBC, which is essential for meeting the specified requirements. Options B and C do not align with the requirements of prioritization and resiliency needed for the deployment.
