Exam MS-720 topic 2 question 2 discussion

Network sites allow you to apply bandwidth and QoS policies to specific physical locations. By defining them, you can implement roaming policies that dynamically control attributes such as IP video and bit rate, improving call quality based on location. The assignment of usage locations in the Admin Center manages numbers and services in different regions, ensuring that Teams Phone policies and features are applied according to geographic location, maintaining regulatory compliance and optimizing resources. Configuring country or region preferences on the SBC can influence media routing, but does not replace the need to define a network topology with network sites and usage locations to manage roaming bandwidth policies.

I think it should be B and D: B. Create a network site. D. Set Preferred country or region for media traffic for the Session Border Controller (SBC). Explanation: B. Creating a network site is necessary to group the locations and define the network bandwidth policies. Network sites are defined based on the physical location of the user or the device, and they are used to apply policies for media traffic, such as audio and video calls. D. Setting the Preferred country or region for media traffic for the Session Border Controller (SBC) is necessary to ensure that media traffic is routed to the nearest SBC, based on the location of the user or the device. This reduces latency and provides better call quality. and not A as : A. Adding the Teams client public IP addresses to the Trusted IPs list is not relevant to creating a network topology for roaming bandwidth policies. This action is used to bypass multi-factor authentication (MFA) and conditional access policies for Teams client connections from trusted IP addresses.

A and B as you can add Network Roaming Policy under Network Sites.
