You must design a highly available Direct Routing deployment. The business requires continued PSTN calling if one SBC fails and also if a single network path fails. Which design best meets the requirement?

After implementing QoS, your network team says DSCP markings from Teams clients are being stripped somewhere. You need to prove whether packets are leaving the client with the expected DSCP values. What is the best method?

Your network team is implementing Quality of Service (QoS) for Teams. They ask which traffic type must receive the highest priority to reduce user-perceived issues during poor network conditions. Which Teams workload should be prioritized highest?

You manage a Teams Rooms deployment across multiple sites. Devices intermittently show as "Offline" in the Teams admin center, but on-site users report the rooms can still join meetings. You need a centralized way to validate whether the issue is with device sign-in/health telemetry versus general internet access. What is the best next step?
