Learn the step-by-step process to enable Quality of Service (QoS) markers in Microsoft Teams admin center to prioritize real-time media traffic and resolve poor audio/video quality in meetings.

Question
You have a Microsoft Teams deployment.
Users report that audio and video during Teams meetings is poor quality.
The network team decides to prioritize real-time media traffic and applies the necessary configuration settings to the network.
You need to configure Teams to use the updated network settings.
What should you do in the Microsoft Teams admin center?
Select only one answer.
A. From Call Quality Dashboard, upload tenant data.
B. From Meeting settings, configure Quality of Service (QoS) markers.
C. From Network and Locations, configure switches.
D. From Network planner, add personas.
Answer
To resolve poor audio and video quality in Microsoft Teams meetings after the network team has prioritized real-time media traffic, follow these steps:
B. From Meeting settings, configure Quality of Service (QoS) markers.
Explanation
You need to configure QoS markers from Meeting settings to use a network that was configured to prioritize QoS markers.
Enable QoS Markers
Navigate to Meetings > Meeting settings in the Microsoft Teams admin center. Under Network, turn on Quality of Service (QoS) markers for real-time media traffic. This action tags Teams’ audio, video, and screen-sharing packets with DSCP values (e.g., 46 for audio, 34 for video), allowing network devices to prioritize this traffic.
Port Configuration
Specify custom port ranges for each media type (e.g., 50,000–50,019 for audio, 50,020–50,039 for video) if required. This ensures traffic is classified correctly.
End-to-End Coordination
While enabling QoS in Teams marks packets, the network team must apply matching DSCP-based prioritization rules on routers, switches, and fireboards.
Why Other Options Are Incorrect
A. Call Quality Dashboard: Used for monitoring call metrics, not configuring QoS.
C. Network and Locations: Manages physical network hardware (e.g., switches, subnets), not QoS tagging.
D. Network Planner: Assesses bandwidth requirements but doesn’t implement QoS.
By enabling QoS markers in Meeting settings, Teams aligns with the network’s prioritization rules, reducing jitter and packet loss for improved meeting quality.
