MS-700 Manage Meetings and Calling Practice Question
Your company is deploying Dynamic E911 for Microsoft Teams. Which TWO of the following are required to ensure the correct location is sent to the Emergency Response Center (ERC)?
⚠ Common exam trap
MS-700 often tests the misconception that a Calling Plan license is required for Dynamic E911, but the key requirements are network mapping and Location Services.
Answer choices
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
✓
A mapping of network subnets or Wi-Fi access points to emergency addresses.
Option A is correct because Dynamic E911 relies on the network topology information you upload to Microsoft (the Emergency Location Mapping, or ELIN/subnet-to-civic-address mapping) so Teams can determine the caller's location from the subnet or Wi-Fi access point the client is connected to. Option C is correct because the client must be able to obtain its position: the OS location service must be enabled and the Teams client must be permitted to use location, otherwise Teams cannot pass the detected address to the ERC. Option B is not required because Dynamic E911 is a location-routing feature and does not depend on every user having a Calling Plan license. Option D is wrong because Dynamic E911 is designed to avoid per-desk phone number configuration by dynamically detecting location. Option E is not required because a dedicated VLAN for certified IP phones is a network design choice, not a prerequisite for Dynamic E911 location detection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A mapping of network subnets or Wi-Fi access points to emergency addresses.
Why this is correct
For Teams to provide a dynamic location, the administrator must upload the organization's network topology, including subnets, switches, and wireless access points. These network elements are then linked to specific civic addresses and locations, allowing the system to pinpoint where a user is located when they place an emergency call.
- ✗
Assignment of a Calling Plan license to every user in the tenant.
Why it's wrong here
While users need a way to make calls, Dynamic E911 works across Calling Plans, Direct Routing, and Operator Connect. A specific Calling Plan license is not the technical requirement for the location-tracking mechanism itself, as location services are a core part of the Teams Phone infrastructure regardless of the PSTN provider.
- ✓
Enabling 'Location Services' on the user's operating system and Teams client.
Why this is correct
The Teams client must have permission to access location data from the underlying operating system to determine its proximity to known network markers. If location services are disabled at the OS level, the client may fail to retrieve the necessary coordinates or network identifiers needed to look up the emergency address.
- ✗
Configuring a different phone number for every physical desk in the office.
Why it's wrong here
Dynamic E911 is designed to avoid the need for static, desk-specific phone numbers by using the network environment to determine location. One phone number can be used across multiple locations, and the system will dynamically provide the current physical address to emergency services based on where the device is plugged in.
- ✗
A dedicated VLAN for all Microsoft Teams certified IP desk phones.
Why it's wrong here
While VLANs can be used as a network identifier for location mapping, they are not a strict requirement for Dynamic E911 to function. Location can also be determined by subnets or individual switch ports. A dedicated VLAN is a network management best practice but not a functional prerequisite for emergency address delivery.
