Zorluk: OrtaMicrosoft Entra ID Authentication and Conditional Access

Elysian Healthcare is designing a hybrid identity and access management solution for its Microsoft Entra ID tenant. The organization currently synchronizes user accounts from an on-premises Active Directory Domain Services (AD DS) domain.

The solution must meet the following requirements:
- Users must sign in to cloud services using their on-premises passwords.
- Users must be prompted for multi-factor authentication (MFA) when accessing any Azure management portal from an untrusted network.
- To prevent accidental tenant lockout during a service outage, a dedicated cloud-only emergency-access account must remain functional without MFA requirements.
- Administrative privileges for Azure resources must be granted dynamically on-demand for a limited time rather than being permanently assigned.
- On-premises infrastructure footprint and administrative overhead must be minimized.

Which of the following designs meets all of the requirements?

  1. Implement directory synchronization using Password Hash Synchronization (PHS). Create a Conditional Access policy requiring MFA for all users that excludes the emergency-access account. Configure Microsoft Entra Privileged Identity Management (PIM) with eligible role assignments.Cevap
  2. B
    Implement directory synchronization by deploying on-premises Active Directory Federation Services (AD FS) and Web Application Proxy servers. Create a Conditional Access policy requiring MFA for all users that excludes the emergency-access account. Configure Microsoft Entra Privileged Identity Management (PIM) with eligible role assignments.
  3. C
    Implement directory synchronization using Password Hash Synchronization (PHS). Create a Conditional Access policy requiring MFA for all administrative users, including all global administrators and the emergency-access account. Configure Microsoft Entra Privileged Identity Management (PIM) with eligible role assignments.
  4. D
    Implement directory synchronization using Password Hash Synchronization (PHS). Create a Conditional Access policy requiring MFA for all users that excludes the emergency-access account. Configure Microsoft Entra Privileged Identity Management (PIM) with active role assignments.

Cevap

Implement directory synchronization using Password Hash Synchronization (PHS). Create a Conditional Access policy requiring MFA for all users that excludes the emergency-access account. Configure Microsoft Entra Privileged Identity Management (PIM) with eligible role assignments.
The correct design utilizes Password Hash Synchronization (PHS) to synchronize on-premises credentials to Microsoft Entra ID with the lowest administrative overhead and server footprint. It implements a Conditional Access policy for MFA that excludes a cloud-only emergency-access account to prevent tenant lockout. Finally, it uses eligible role assignments in Microsoft Entra Privileged Identity Management (PIM) to ensure administrative privileges are requested and granted dynamically on-demand rather than remaining permanently assigned.

Adım Adım Çözüm

1
Evaluate the hybrid identity synchronization requirement.
Password Hash Synchronization (PHS) is selected.
PHS allows users to sign in with their on-premises passwords while minimizing on-premises server footprint and administrative overhead compared to Active Directory Federation Services (AD FS).
2
Evaluate the emergency access and Conditional Access requirement.
Excluding the emergency-access account from the MFA Conditional Access policy.
This prevents administrative lockout in the event of an identity synchronization failure or a primary MFA service outage.
3
Evaluate the dynamic administrative access requirement.
Configure Microsoft Entra Privileged Identity Management (PIM) with eligible role assignments.
Eligible assignments require users to explicitly activate their roles on-demand for a limited duration, whereas active assignments make the access permanent.
