MS-740 Teams Network and Connectivity Troubleshooting 1 — Questions and Answers
Question 1: Which Microsoft tool is specifically designed to test network readiness and quality for Microsoft Teams before deployment?
- Network Performance Monitor
- Microsoft Teams Network Assessment Tool (Correct answer)
- Wireshark Packet Analyzer
- Azure Network Watcher
Correct answer: Microsoft Teams Network Assessment Tool
The Microsoft Teams Network Assessment Tool performs network connectivity tests, simulating Teams media traffic to validate readiness.
Question 2: What is the maximum recommended packet loss percentage for acceptable Teams audio quality according to Microsoft?
- 1% (Correct answer)
- 5%
- 10%
- 0.5%
Correct answer: 1%
Microsoft recommends packet loss below 1% for Teams audio; higher values cause noticeable degradation in call quality.
Question 3: Which UDP port range does Microsoft Teams use for media traffic including audio, video, and screen sharing?
- 443 TCP only
- UDP 3478-3481 (Correct answer)
- TCP 5061
- UDP 50000-50059
Correct 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.
Question 4: 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?
- Usage reports
- Call Quality Dashboard (CQD) (Correct answer)
- Teams activity report
- Audit log
Correct answer: Call Quality Dashboard (CQD)
CQD (Call Quality Dashboard) provides aggregate, tenant-wide call quality metrics and trending data for identifying systemic network issues.
Question 5: What is the primary purpose of Microsoft Teams TURN (Traversal Using Relays around NAT) servers?
- Authenticating Teams users
- Relaying media traffic when direct peer-to-peer connection cannot be established (Correct answer)
- Resolving DNS for Teams endpoints
- Enforcing calling policies
Correct 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.
Question 6: What is the maximum recommended jitter value for Teams audio in real-time communications?
- 30ms (Correct answer)
- 100ms
- 50ms
- 200ms
Correct answer: 30ms
Microsoft recommends jitter below 30ms for Teams audio; higher jitter causes choppy or robotic-sounding audio.
Question 7: Which protocol does Microsoft Teams primarily use to transport real-time audio and video media?
- TCP with TLS
- HTTP/2
- SRTP over UDP (Correct answer)
- SIP over TLS
Correct answer: SRTP over UDP
Teams uses SRTP (Secure Real-time Transport Protocol) over UDP for media, providing encryption with low-latency delivery.
