MS-740 Teams Network and Connectivity Troubleshooting 2 — Questions and Answers
Question 1: What is the primary benefit of implementing Quality of Service (QoS) for Microsoft Teams traffic?
- Encrypting Teams data in transit
- Prioritizing Teams traffic with DSCP markings to ensure consistent quality (Correct answer)
- Automatically increasing bandwidth for Teams
- Load balancing Teams across multiple servers
Correct answer: Prioritizing Teams traffic with DSCP markings to ensure consistent quality
QoS uses DSCP markings to signal network devices to prioritize Teams media packets over less time-sensitive traffic.
Question 2: Which DSCP value does Microsoft recommend for Teams audio traffic when implementing Quality of Service?
- 46 (Expedited Forwarding) (Correct answer)
- 34 (AF41)
- 18 (AF21)
- 0 (Best Effort)
Correct answer: 46 (Expedited Forwarding)
DSCP value 46 (Expedited Forwarding / EF) is recommended for Teams audio as it receives the highest priority queuing on network devices.
Question 3: A user in a branch office cannot connect to Teams but can access other websites normally. What should you investigate first?
- The user's Microsoft 365 license assignment
- Proxy server settings and whether Teams URLs are bypassed (Correct answer)
- Active Directory group membership
- Teams desktop app version
Correct answer: Proxy server settings and whether Teams URLs are bypassed
Proxy servers often block or interfere with Teams traffic; Microsoft 365 Optimize-category URLs including Teams should be bypassed in proxy configurations.
Question 4: What is the purpose of the Network Planner tool in the Microsoft Teams admin center?
- Monitoring real-time call quality
- Calculating bandwidth requirements and modeling network readiness for Teams deployment (Correct answer)
- Viewing per-user call history
- Configuring network policies in Teams
Correct answer: Calculating bandwidth requirements and modeling network readiness for Teams deployment
Network Planner calculates expected Teams bandwidth consumption based on persona types and site information to help plan network capacity.
Question 5: When reviewing Microsoft 365 endpoint categories for network optimization, which category of Teams URLs should receive the highest network priority and VPN split-tunnel treatment?
- Default
- Allow
- Optimize (Correct answer)
- Required
Correct answer: Optimize
The 'Optimize' category contains the most latency-sensitive Microsoft 365 endpoints (including Teams media) that must have direct internet paths for best performance.
Question 6: What is the maximum recommended round-trip time (RTT) for Teams audio according to Microsoft's network quality targets?
- 500ms
- 100ms (Correct answer)
- 200ms
- 50ms
Correct answer: 100ms
Microsoft recommends RTT below 100ms for Teams audio; higher latency causes noticeable delays and conversation quality issues.
Question 7: Which Microsoft 365 admin center feature allows administrators to test network egress performance and latency to Microsoft Teams and other services?
- Service health dashboard
- Microsoft 365 network connectivity test (Correct answer)
- Compliance center connectivity check
- Exchange connectivity analyzer
Correct answer: Microsoft 365 network connectivity test
The Microsoft 365 network connectivity test measures egress IP geolocation, latency, and connectivity to nearby Microsoft front-door servers.
