MS-700 Monitor, Report on, and Troubleshoot Teams Practice Question
A user is experiencing 'Poor' quality calls. You verify the network in Call Analytics and see consistent 'High Packet Loss' on the client side. What is the most likely cause?
⚠ Common exam trap
MS-700 often tests the ability to distinguish between client-side and server-side issues in Call Analytics; candidates may incorrectly blame Microsoft 365 or policies when the data clearly shows a client-side network problem.

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
✓
Local network congestion
Consistent high packet loss on the client side in Call Analytics points to a problem in the local network path, not the Microsoft 365 service. Local network congestion—such as oversaturated Wi-Fi, a failing switch port, or heavy bandwidth consumption—causes packets to be dropped before they reach Teams. Since the issue is isolated to the client side and is persistent, a local network condition is the most likely cause.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Microsoft 365 server-side outage
Why it's wrong here
Server-side outages would affect all users in a region rather than causing localized packet loss for a single user. If the packet loss is client-side, the issue is isolated to the path between the user and the internet, not a global service failure.
- ✓
Local network congestion
Why this is correct
High packet loss at the client level is almost always caused by congestion on the local network or Wi-Fi interference. When the local network is saturated or the wireless connection is unstable, packets are dropped before they can be successfully transmitted to the internet.
- ✗
Teams policy misconfiguration
Why it's wrong here
Policies control features and access, not the physical transmission quality of media packets. A misconfigured policy might prevent a user from joining a meeting or using screen sharing, but it will not cause physical network packet loss during a call.
- ✗
Incompatible device driver
Why it's wrong here
While drivers can cause audio distortion or microphone issues, they do not cause network-level packet loss. Packet loss is a metric of data transmission failure across a network medium, which is independent of the local hardware's audio input/output processing capability.
