Collaboration Communications Systems Engineer — Question 98

Your company has offices in Paris and London.
You are migrating from an on-premises PBX telephony solution to a Microsoft Teams Phone deployment that uses Direct Routing. You plan to use the existing telephony carrier. The new solution will provide telephony services to users in Both offices.
You need to recommend a solution that is the most resistant to possible failures. The solution must ensure that calls are routed through each user's respective office.
Which two actions should you include in the recommendation? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

Answer options

• A. Configure voice routing policies for each office.
• B. Configure a single voice routing policy for all users.
• C. Deploy a highly available Session Border Controller (SBC) pair to each office.
• D. Deploy one Session Border Controller (SBC) to each office. Configure the SBCs as a high-availability pair.

Correct answer: A, C

Explanation

The correct answers are A and C. Configuring voice routing policies for each office ensures that calls are directed appropriately based on the user's location, enhancing reliability. Deploying a highly available SBC pair at each office provides redundancy, minimizing the risk of downtime. Options B and D do not offer the same level of resilience and proper routing as the selected answers.
