Question
You have a Microsoft Teams deployment.
Your company is planning a corporate, virtual meeting for 1,000 participants. The event will include live presentations and videos that can significantly affect the internal network and internet bandwidth.
You need to recommend a solution to reduce network traffic for the event and ensure quality audio and video for all the participants.
What should you recommend?
Select only one answer.
A. Configure a network roaming policy.
B. Enable Quality of Service (QoS) markers.
C. Use a Teams live event with an enterprise content delivery network (eCDN).
D. Use a webinar for the presentation.
Answer
C. Use a Teams live event with an enterprise content delivery network (eCDN).
Explanation
The answer is eCDN with a live event. The question asks how to minimize traffic on the local network. The only solution is an eCDN solution that delivers a single stream to participant’s workstations.
Why This Solution Works
Microsoft Teams live events paired with an eCDN address network congestion and bandwidth limitations during large-scale broadcasts by:
Reducing Bandwidth Consumption
- eCDN uses peer-to-peer (P2P) technology to distribute video streams within the corporate network, minimizing reliance on external internet bandwidth. For example, a 2 Mbps stream with 1,000 viewers would require 2 Gbps without eCDN, but with 90% efficiency, bandwidth drops to 200 Mbps.
- Mesh networks automatically scale as viewers join, sharing content locally to reduce redundant data requests.
Ensuring High-Quality Streaming
- Microsoft eCDN supports adaptive bitrate streaming (720p maximum resolution), dynamically adjusting video quality to prevent buffering. Advanced analytics monitor network performance and viewer experience in real time.
Scalability and Compliance
- Teams live events support up to 20,000 authenticated attendees, far exceeding standard meeting limits.
- eCDN integrates with Microsoft’s compliance framework, ensuring secure content delivery to authorized users only.
Why Other Options Fail
A. Network roaming policy: Optimizes device connectivity but does nothing to reduce bandwidth saturation from video streaming.
B. QoS markers: Prioritizes network traffic but doesn’t lower total bandwidth consumption.
D. Webinars: Limited to 1,000 interactive attendees and lacks native eCDN integration for traffic optimization.
Implementation Steps
- Enable Microsoft eCDN in Teams Admin Center under Meetings > Live Event Settings.
- Validate network configurations (e.g., allow HTTPS/UDP traffic to Microsoft eCDN domains).
- Conduct pre-event testing with subnet mapping and silent traffic simulations.
By combining Teams live events with eCDN, organizations eliminate network bottlenecks while delivering seamless, high-quality broadcasts to thousands of participants.
