MS-700 Monitor, Report on, and Troubleshoot Teams Practice Question
Exhibit
{"PolicyID": "123", "MediaMode": "TCP_Only", "MinPort": 50000, "MaxPort": 50010}Refer to the exhibit. What is the impact of this Teams media policy on call quality?
⚠ Common exam trap
MS-700 often tests the misconception that any media policy setting improves quality or security, when in fact restrictive settings like disabling UDP or capping bit rate degrade call quality.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Degraded audio and video quality.
The exhibit shows a Teams media policy with a setting that restricts media traffic, such as disabling UDP or forcing a specific codec/transport that increases overhead. When Teams cannot use UDP for media, it falls back to TCP, which introduces retransmissions and jitter, directly degrading audio and video quality. Therefore, the impact is degraded call quality rather than improved security or reduced latency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Improved security for media streams.
Why it's wrong here
Forcing TCP does not improve security; media in Teams is already encrypted via SRTP regardless of the transport protocol. This change only negatively impacts performance and latency, as TCP's overhead and retransmission logic are unsuited for the real-time requirements of voice and video traffic.
- ✗
Reduced latency during calls.
Why it's wrong here
Forcing TCP increases latency, not reduces it. Because TCP waits for acknowledgments and retransmits lost segments, the total time to deliver media packets is much higher than UDP, which is designed for speed and real-time delivery in modern collaborative environments.
- ✓
Degraded audio and video quality.
Why this is correct
TCP is not designed for real-time media because its retransmission mechanisms introduce significant latency and jitter. Forcing TCP-only mode bypasses the high-performance UDP delivery optimized for Teams, resulting in noticeable degradation of both audio and video quality during meetings and calls.
- ✗
Increased compatibility with older firewalls.
Why it's wrong here
While some very old firewalls might struggle with UDP, the cost to performance is too high to justify this as a standard practice. Modern network infrastructure should be updated to support the necessary UDP ports rather than sacrificing user experience via this restrictive configuration.
