Microsoft 365 Administrator Expert MS-102 Practice Question

A company uses a Microsoft Entra tenant that synchronizes on-premises identities by using Microsoft Entra Connect. A Conditional Access policy named Require MFA targets all users and all cloud apps and allows access only if multi-factor authentication (MFA) is satisfied. A user reports that when signing in from a Windows 7 computer that runs Outlook 2010, access is denied without any MFA prompt. You review the sign-in log and see the failure reason AADSTS50079: The user is required to use multi-factor authentication. What is the most likely cause of the failed sign-in?

  • The user is connecting with a legacy authentication client that cannot perform MFA, so the Conditional Access policy blocks the request.

  • Per-user MFA is set to Enforced on the account, which conflicts with the Conditional Access policy and denies access.

  • The user's password hash has not synchronized to Microsoft Entra ID, preventing the MFA prompt from being issued.

  • Self-service password reset (SSPR) is disabled for the user, so MFA registration cannot be completed during sign-in.
