Quick Answer
The answer is Password Writeback with password change notification. This feature is correct because it enables on-premises password changes to synchronize back to Microsoft Entra ID in near real-time, and the accompanying notification triggers a forced re-authentication for active sessions within minutes, invalidating stale tokens and ensuring users must present the new password. On the AZ-500 exam, this scenario tests your understanding of hybrid identity security controls, specifically how to enforce re-authentication after a password change without relying on user-initiated sign-out. A common trap is confusing this with simple password hash synchronization, which only syncs the hash for authentication but does not force session revalidation. Remember the key distinction: writeback plus notification equals active session enforcement. For a memory tip, think “Writeback Warns” — the writeback writes the new password, and the notification warns Entra ID to force re-auth.
This AZ-500 practice question tests your understanding of secure identity and access. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your organization uses Microsoft Entra ID and has a hybrid identity setup with password hash synchronization. You need to implement a solution that detects password changes on-premises and forces re-authentication for active sessions within minutes. Which feature should you enable?
Azure AD Connect Health
Why wrong: Monitors sync health, not real-time action.
Password Writeback with password change notification
Synchronizes password changes and can trigger re-authentication via Conditional Access.
Azure AD Domain Services
Why wrong: For domain-joined VMs.
Seamless SSO
Why wrong: Provides automatic sign-in, not session revocation.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Password Writeback with password change notification
Option B, Password Writeback with password change notification, is correct because it enables on-premises password changes to be synchronized back to Microsoft Entra ID in near real-time. When a password is changed on-premises, the password change notification triggers a re-authentication requirement for active sessions within minutes, ensuring that users with stale tokens are forced to re-authenticate using the new password.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Azure AD Domain Services

Seamless SSO
Why it's wrong here
Provides automatic sign-in, not session revocation.
Common exam traps
The trap here is that candidates often confuse Password Writeback with Seamless SSO, thinking that SSO handles password changes, when in fact Seamless SSO only provides silent authentication and does not detect or propagate password changes to force re-authentication.
Detailed technical explanation
Password Writeback uses the Microsoft Entra Connect synchronization engine to write password changes from on-premises Active Directory back to Entra ID. The password change notification feature leverages the 'On-Premises Password Change Notification' event, which triggers a token revocation for the user's active sessions within minutes by updating the password hash and invalidating existing refresh tokens. This ensures that any session with a token issued before the password change is rejected upon the next resource access attempt.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
