Microsoft Microsoft Certifications AZ-400 Questions & Answers

• Question 511:

  You have a private distribution group that contains provisioned and unprovisioned devices.

  You need to distribute a new iOS application to the distribution group by using Microsoft Visual Studio App Center.

  What should you do?

  A. Register the devices on the Apple Developer portal.

  B. Add the device owner to the organization in App Center.

  C. Create an unsigned build.

  D. Add the device owner to the collaborators group.

  Correct Answer: A

  Distribute a new release.

  When you distribute a new release to a group that doesn't have automatic device management enabled, a Devices step is part of the wizard. The step checks if you have unprovisioned devices in the distribution group; if this happens, you can

  check the Register devices and re-sign app checkbox. App Center then runs three operations for you:

  1.

  Register new device IDs in the Apple Developer portal.

  2.

  Add the devices to the provisioning profile and download it.

  3.

  Re-sign the uploaded binary so that all testers can install it. Reference: https://docs.microsoft.com/en-us/appcenter/distribution/auto-provisioning
