Question

You have a Microsoft 365 subscription and a Teams Phone deployment. You purchase 50 certified Teams devices to be used as common area phones. To the subscription, you upload a file that contains the MAC address of each device. You need to ensure that field technicians can provision each device. What should you configure?

Options

  • Aa Teams IP Phone policy
  • Ba configuration profile
  • Can app setup policy
  • Dverification codes

Explanation

To enable field technicians to provision common area Teams phones after their MAC addresses are uploaded, you should configure a method for secure device sign-in.

Common mistakes.

  • A. Teams IP Phone policies are used to manage features and settings for already provisioned IP phones, not to facilitate the initial physical provisioning process by a technician.
  • B. While configuration profiles are relevant to device management, 'verification codes' is the specific mechanism for initial device authentication and sign-in for Teams devices during provisioning.
  • C. App setup policies control which applications are available and pinned in the Teams client for users, not the process of provisioning a physical Teams device itself.
