MS-700 Configure and Manage a Teams Environment Practice Question
A company is implementing Location-Based Routing (LBR) to comply with local telecommunications regulations. Which Microsoft Teams component is primarily responsible for enforcing LBR restrictions when a user attempts to make a PSTN call?
⚠ Common exam trap
MS-700 often tests the misconception that the SBC enforces LBR, when in fact the network site determines the routing policy, and the SBC only executes the routing decision.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Network Site associated with the user's IP address
Location-Based Routing (LBR) in Microsoft Teams enforces restrictions based on the user's physical location, which is determined by the Network Site associated with the user's IP address. When a user attempts a PSTN call, Teams checks the network site to determine if the call is allowed based on the LBR policy. The SBC enforces the routing but the decision is based on the network site configuration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The Teams Phone Mobile provider
Why it's wrong here
Teams Phone Mobile providers manage the integration of mobile numbers with Teams but are not responsible for enforcing internal LBR policies. LBR is a tenant-side configuration that applies to how the Microsoft Teams service handles calls based on the network site information provided by the administrator.
- ✓
The Network Site associated with the user's IP address
Why this is correct
LBR uses the network site configuration, which maps IP subnets to physical locations. When a user makes a call, Teams checks their current IP against the defined network sites. If the site is configured for LBR, the service enforces the routing rules associated with that specific geographical location.
- ✗
The Azure Virtual Desktop agent
Why it's wrong here
While Teams can run in AVD, the AVD agent itself has no role in telecommunications compliance or LBR enforcement. LBR is a function of the Teams calling service and its interaction with the defined network topology, regardless of whether the client is running on a physical or virtual machine.
- ✗
The SBC (Session Border Controller) hardware
Why it's wrong here
Although the SBC handles the actual signaling and media for PSTN calls in a Direct Routing scenario, the decision to allow or block the call based on the user's location is made by the Microsoft Teams service policy engine before the call ever reaches the SBC for routing.
