Your company wants to use an Azure Active Directory (Azure AD) hybrid identity solution.
You need to ensure that users can authenticate if the internet connection to the on-premises Active Directory is unavailable. The solution must minimize authentication prompts for the users.
What should you include in the solution?
A. password hash synchronization and Azure AD Seamless Single Sign-On (Azure AD Seamless SSO)
B. pass-through authentication and Azure AD Seamless Single Sign-On (Azure AD Seamless SSO)
C. an Active Directory Federation Services (AD FS) server
Correct Answer: A
With Password hash synchronization + Seamless SSO the authentication is in the cloud.
Pass-through Authentication and federation rely on on-premises infrastructure.
