Collaboration Communications Systems Engineer — Question 83

You have a Microsoft 365 tenant that has Modem authentication enabled for all services Multi-factor authentication (MFA) is enforced for all users.
You are deploying Microsoft Teams Rooms.
The first time you attempt to sign in to a Teams Rooms, you receive an error message indicating that the device cannot sign in to Teams.
You verify that Modern authentication is enabled in Teams Rooms.
What prevents you from signing in?

Answer options

• A. Teams Rooms must be domain-joined first
• B. MFA is unsupported in Teams Rooms
• C. The Microsoft Authenticator app is not configured for the Teams Rooms account
• D. The Teams Rooms account is not licensed for Microsoft Intune

Correct answer: B

Explanation

The correct answer is B because Microsoft Teams Rooms does not support Multi-factor authentication, making it impossible to sign in when MFA is enforced. Option A is incorrect as domain joining is not a prerequisite for signing in. Option C is not relevant since the issue is with MFA support, and option D is also incorrect because licensing for Intune does not affect Teams Rooms' ability to authenticate with MFA.
