MS-700 Question #121: Real Exam Question with Answer & Explanation

Question

Your company is opening a branch office in Miami. The office uses a network range of 10.10.10.0/24. You need to restrict Teams bandwidth to 1,000 Kbps for all the users working at the Miami office. The solution must NOT affect other offices. To complete this task, sign in to the Microsoft 365 portal.

Explanation

This question tests the ability to configure location-based bandwidth restrictions in Microsoft Teams using Network Topology and Network Roaming Policies, scoped specifically to a subnet so only one office is affected.

Approach. The correct approach is to open the Teams Admin Center (accessible via the Microsoft 365 portal at admin.teams.microsoft.com), then navigate to Locations > Network topology. First, create a Network Site for the Miami office and associate the subnet 10.10.10.0/24 with it. Next, create a Network Roaming Policy (under Meetings > Network roaming policies) and set the bandwidth limit to 1,000 Kbps for the relevant media types (audio, video, screen sharing). Finally, assign that roaming policy to the Miami network site. Because the policy is bound to the subnet rather than to user accounts, only users physically connecting through the Miami network range are affected - all other offices remain unchanged.

Concept tested. Microsoft Teams Network Roaming Policies and Network Topology (trusted IPs / subnets) - the mechanism for applying location-aware, subnet-scoped QoS and bandwidth controls in Microsoft Teams without impacting users at other sites.
