Exam MS-100 topic 3 question 41 discussion

Smartcard is the key word.

Answer: B Explanation References: Federation with Active Directory Federation Services (AD FS) is required to allow users to sign in by using smart card-based certificates. Federated authentication When you choose this authentication method, Azure AD hands off the authentication process to a separate trusted authentication system, such as on-premises Active Directory Federation Services (AD FS), to validate the user's password. The authentication system can provide additional advanced authentication requirements. Examples are smartcard-based authentication or third-party multifactor authentication.
