Microsoft 365 Administrator Expert MS-102 Practice Question

Contoso implements Microsoft Entra Connect with Pass-through Authentication (PTA) and Seamless Single Sign-On (SSO). The CIO wants to ensure that users can still sign in to Microsoft 365 services if every PTA agent or the entire corporate network becomes unreachable for several hours. The existing sign-in behavior must remain unchanged while the PTA infrastructure is healthy, and administrators are willing to take manual action if an outage occurs.

Which action should you take to provide a backup authentication method that can be switched to during an extended PTA outage without affecting day-to-day sign-ins?

  • Enable a Seamless SSO policy that forces Azure AD to fall back to cloud-only authentication when PTA becomes unavailable.

  • Deploy two additional PTA agents on separate servers and place them in the same Active Directory site.

  • Configure federation with AD FS and set Azure AD to use federation as a secondary authentication method.

  • Enable Password Hash Synchronization and retain Pass-through Authentication as the primary sign-in method.
