- Teams admin center Call Analytics (Correct answer)
- Microsoft 365 Message Center
- Azure Active Directory audit logs
- Power BI usage reports
Correct answer: Teams admin center Call Analytics
Call Analytics in the Teams admin center provides per-call audio quality data including jitter, packet loss, and latency.
Question 2: What minimum upload bandwidth is recommended per user for HD video in Teams meetings?
- 1.5 Mbps (Correct answer)
- 500 Kbps
- 3 Mbps
- 4 Mbps
Correct answer: 1.5 Mbps

VPN split tunneling allows Teams media UDP traffic to bypass the VPN tunnel, improving quality significantly.
Question 6: Which metric in Call Quality Dashboard (CQD) best indicates packet loss affecting audio quality?
- Audio Poor Stream Ratio (Correct answer)
- Jitter average
- Round Trip Time
- Packet utilization
Correct answer: Audio Poor Stream Ratio
The Audio Poor Stream Ratio in CQD measures the percentage of call streams classified as poor due to metrics including packet loss.
