Teams Phone troubleshooting and number management were the areas that slowed me down, so I reviewed routing options and how licensing affects features. Once I tied it back to operational tasks, I passed the Microsoft Collaboration Communications Systems Engineer exam.

Monitoring and troubleshooting questions required interpreting Call Quality Dashboard and call analytics to diagnose packet loss, jitter or routing issues and choosing the right logs or reports to collect. I managed to pass after spending time with CQD, call analytics and learning typical quality thresholds and where to find SIP traces in the Teams admin center.

I found the exam questions were scenario driven, so I practiced explaining why one architecture was better than another for a given tenant and network constraint. That kind of reasoning helped me stay calm during the test and I passed.

Questions on meetings, webinars and town halls often came as comparisons or flow problems, such as selecting appropriate meeting policies, configuring registration and Q&A, or choosing Live Events versus a webinar for scale. I passed by practicing different meeting types in a tenant and studying meeting policy precedence, presenter roles and attendee experience details.

The trickiest part for me was Teams Rooms and device management, especially knowing what you can control in the Teams admin center versus on the device itself. After building a small lab and running through common failure scenarios, I passed the exam.

Teams Phone questions focused on practical configuration challenges like setting voice routing policies, emergency calling and deciding between Direct Routing and Calling Plans under ambiguous requirements. I passed by building voice routing scenarios in a lab and studying PSTN connectivity, SIP trunk basics and policy precedence.

MS-721 leaned heavily on real world design choices, so I spent most of my prep mapping requirements to Teams Phone and calling policies instead of memorizing menus. That approach paid off and I passed on the first try.

Plan and design collaboration communications systems questions were very scenario-driven, asking me to choose SBC placement, redundancy patterns and licensing for a multinational rollout while weighing trade-offs. I passed the exam and, after reviewing QoS, PSTN options and capacity planning and practising Pass4Success question sets for quick review, I cleared it in a short time.

Quick note Direct Routing and SBC configuration was much trickier than I expected. Hands-on labs and diagramming call flows helped me get it straight.

Abdullah Malik

Selected Answer: **B** Direct Routing configuration is heavily dependent on proper SBC pairing with the Teams Phone System, and the call flow diagrams make it obvious why the SBC acts as the gateway between PSTN and Teams. Anyone who skips diagramming the signaling path will get confused fast on the exam.
