Question
Your company has recently expanded its operations to a new location with a low bandwidth network. The company uses Microsoft Teams extensively for its communication and collaboration needs.
You need to ensure that the Teams client dynamically picks up settings based on the network site it connects to, while also controlling the use of IP Video and Media bit rate attributes to optimize the usage of the available bandwidth.
What should you do?
Select only one answer.
A. Create a new TeamsNetworkRoamingPolicy with AllowIPVideo set to false and MediaBitRateKb set to a lower value. Then assign this policy to the new network site.
B. Create a new TeamsNetworkRoamingPolicy with AllowIPVideo set to true and MediaBitRateKb set to a higher value. Then assign this policy to the new network site.
C. Modify the existing TeamsNetworkRoamingPolicy to set AllowIPVideo to false and reduce the MediaBitRateKb. Then assign this policy to the new network site.
D. Modify the existing TeamsNetworkRoamingPolicy to set AllowIPVideo to true and increase the MediaBitRateKb. Then assign this policy to the new network site.
Answer
To address low-bandwidth network challenges in Microsoft Teams, Option A is correct.
A. Create a new TeamsNetworkRoamingPolicy with AllowIPVideo set to false and MediaBitRateKb set to a lower value. Then assign this policy to the new network site.
Explanation
Creating a new TeamsNetworkRoamingPolicy with AllowIPVideo set to false and MediaBitRateKb set to a lower value will help optimize the usage of the available bandwidth in the new location with a low bandwidth network. This policy can then be assigned to the new network site so that the Teams client dynamically picks up these settings when it connects from this network site. Modifying the existing policy or setting AllowIPVideo to true and increasing the MediaBitRateKb would not be optimal for a low bandwidth network.
When deploying Teams in low-bandwidth environments, TeamsNetworkRoamingPolicy enables dynamic control over video and media bit rates based on network location. Here’s why Option A works:
Disable Video to Reduce Bandwidth
- AllowIPVideo = False prohibits users from enabling video during calls/meetings, freeing significant bandwidth.
- Video consumes up to 2 Mbps per user, so disabling it prioritizes audio and screen-sharing efficiency.
Cap Media Bit Rate
- MediaBitRateKb sets a maximum average bit rate for audio/video streams. Lowering this value (e.g., 300–800 Kbps) prevents excessive bandwidth usage.
- Teams dynamically adjusts video resolution/frame rate under constrained bandwidth, but enforcing a lower bit rate ensures stability in low-speed networks.
Policy Assignment to Network Sites
- After creating the policy, assign it to the new network site via Set-CsTenantNetworkSite.
- Teams clients at this site will automatically apply these settings, overriding default meeting policies.
Why Other Options Fail
- Options B/D (Enable Video/High Bit Rate): Increase bandwidth consumption, worsening performance in low-speed networks.
- Option C (Modify Existing Policy): Risks affecting other sites if the existing policy is shared. Creating a new policy (Option A) isolates settings for the low-bandwidth site.
By implementing Option A, Teams clients at the new site will disable video and use minimal bandwidth while maintaining essential collaboration features.
For further optimization, consider restricting screen-sharing to individual windows and enabling QoS policies.
