MS-700 Manage Meetings and Calling Practice Question
A Teams administrator is configuring a new auto attendant for a main reception line. The auto attendant must allow callers to reach a specific user by entering the user's extension using a custom range of 1000 to 1999. The administrator has already created the auto attendant and assigned a resource account. What should the administrator do next to meet this requirement?
⚠ Common exam trap
Candidates often confuse dial plans or call queues with the auto attendant's built-in dial-by-extension capability, which is configured directly in the auto attendant settings.

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
✓
In the auto attendant settings, enable 'Dial by extension' and specify the extension range 1000-1999.
Auto attendants in Microsoft Teams include a 'Dial by extension' option that can be enabled and configured with a custom extension range. When enabled, callers can enter an extension, and the auto attendant searches the organization's directory for a user with that extension. This is a native feature of auto attendants and does not require additional resource accounts or dial plans.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a call queue and assign the resource account to it, then configure the extension range.
Why it's wrong here
Call queues are used to distribute calls to a group of agents, not to provide dial-by-name or extension directory search. The extension range for an auto attendant is configured directly in the auto attendant settings, not through a call queue. While a call queue can be an option in the auto attendant menu, it does not enable extension dialing. This approach does not meet the requirement.
- ✓
In the auto attendant settings, enable 'Dial by extension' and specify the extension range 1000-1999.
Why this is correct
The auto attendant has a built-in 'Dial by extension' feature that allows callers to enter an extension. By enabling this option and specifying a custom extension range, the auto attendant will search the directory for users with extensions in that range. This directly satisfies the requirement without additional resources.
- ✗
Configure a dial plan with normalization rules for the extension range and assign it to the auto attendant's resource account.
Why it's wrong here
Dial plans and normalization rules are used for number translation during outbound calls, not for auto attendant directory search. While dial plans can affect how numbers are dialed, they do not enable an auto attendant to accept extension input and search the directory. The correct method is to enable dial-by-extension in the auto attendant settings.
- ✗
Create a new resource account for each user in the range and assign them to the auto attendant.
Why it's wrong here
Resource accounts are used for auto attendants and call queues, not for individual users. Creating a resource account per user is unnecessary and does not enable extension dialing. The auto attendant's dial-by-extension feature automatically searches user extensions. This would add complexity without solving the problem.
