Teams Network and Connectivity Troubleshooting Flashcards

Which Microsoft tool is specifically designed to test network readiness and quality for Microsoft Teams before deployment?

Answer: Microsoft Teams Network Assessment Tool

The Microsoft Teams Network Assessment Tool performs network connectivity tests, simulating Teams media traffic to validate readiness.

What is the maximum recommended packet loss percentage for acceptable Teams audio quality according to Microsoft?

Answer: 1%

Microsoft recommends packet loss below 1% for Teams audio; higher values cause noticeable degradation in call quality.

Which UDP port range does Microsoft Teams use for media traffic including audio, video, and screen sharing?

Answer: UDP 3478-3481

Teams uses UDP ports 3478–3481 for media relay (TURN) traffic; these ports must be open outbound to Microsoft IP ranges.

A user reports poor call quality affecting multiple people in the same office. Which Teams admin center tool provides aggregate call quality data across the organization?

Answer: Call Quality Dashboard (CQD)

CQD (Call Quality Dashboard) provides aggregate, tenant-wide call quality metrics and trending data for identifying systemic network issues.

What is the primary purpose of Microsoft Teams TURN (Traversal Using Relays around NAT) servers?

Answer: Relaying media traffic when direct peer-to-peer connection cannot be established

TURN servers act as media relays when firewall or NAT configurations prevent a direct peer-to-peer media path between participants.

What is the maximum recommended jitter value for Teams audio in real-time communications?

Answer: 30ms

Microsoft recommends jitter below 30ms for Teams audio; higher jitter causes choppy or robotic-sounding audio.

Which protocol does Microsoft Teams primarily use to transport real-time audio and video media?

Answer: SRTP over UDP

Teams uses SRTP (Secure Real-time Transport Protocol) over UDP for media, providing encryption with low-latency delivery.
