    AZ-305 · Question 05 · Domain 1.2: Authentication and Authorization

    A highly regulated financial institution is migrating to Microsoft 365 and Azure. They currently use an on-premises Active Directory Domain Services (AD DS) forest.

    The Chief Security Officer (CSO) mandates the following strict requirements:

    1. User passwords or password hashes MUST NOT be synchronized to the cloud under any circumstances.
    2. Users must experience Single Sign-On (SSO) from their domain-joined corporate devices.
    3. If the on-premises internet connection fails, users must not be able to authenticate to cloud services.
    4. The solution must not require inbound ports to be opened on the corporate firewall.

    Which hybrid identity solution should you design?

    Answer options:

    A.

    Password Hash Synchronization (PHS) with Seamless SSO

    B.

    Active Directory Federation Services (AD FS)

    C.

    Pass-through Authentication (PTA) with Seamless SSO

    D.

    Azure AD Domain Services (Azure AD DS)

    How to approach this question

    Evaluate the constraints: No password hashes in cloud eliminates PHS. No inbound ports heavily discourages AD FS. PTA uses outbound agents and validates against on-prem AD.

    Full Answer

    C.Pass-through Authentication (PTA) with Seamless SSO✓ Correct
    Pass-through Authentication (PTA) allows users to sign in to both on-premises and cloud-based applications using the same passwords. It validates users' passwords directly against on-premises Active Directory. It does not sync password hashes to Entra ID. The PTA agents only require outbound ports (443). Because authentication happens on-premises, if the connection drops, cloud authentication fails, meeting all the CSO's strict requirements.

    Common mistakes

    Choosing AD FS. While AD FS keeps authentication on-premises, it requires complex infrastructure and inbound connectivity to the WAP servers, violating the firewall requirement.
