The correct answer is to configure the 'User sign-in frequency' setting under 'User feature' settings to automatically revoke access for users inactive for 90 days. This built-in Microsoft Entra ID feature natively enforces a conditional access session control that prompts reauthentication after a specified period; if a user fails to sign in within that window, their tokens expire and access is effectively revoked. On the AZ-500 exam, this scenario tests your ability to distinguish between native Entra ID controls and more complex or costly alternatives like custom PowerShell scripts or third-party identity governance tools. A common trap is confusing this with Entra ID Identity Governance's access reviews, which require P2 licensing and manual approval, whereas sign-in frequency is a cost-effective P1 feature that operates automatically. Memory tip: think of it as a "session timeout for ghosts"—if they haven't logged in for 90 days, the system locks the door automatically.
AZ-500 Secure identity and access Practice Question
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 has a Microsoft Entra ID tenant with 50,000 users. You are designing a solution to automatically revoke access for users who have not signed in for 90 days. The solution must be cost-effective and use built-in Microsoft Entra ID features. What should you do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure the 'User sign-in frequency' setting in the 'User feature' settings to automatically remove users inactive for 90 days.
Option C is correct because Microsoft Entra ID includes a built-in 'User sign-in frequency' setting under 'User feature' preview that can automatically revoke access for users who have not signed in for a specified period (e.g., 90 days). This feature is cost-effective as it requires no additional licensing beyond the base Entra ID P1 or P2, and it operates natively without custom scripts or external automation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Create a Power Automate flow that triggers monthly to check sign-in logs and disable inactive users.
Why it's wrong here
Not a built-in Microsoft Entra ID feature.
✗
Use Microsoft Entra Connect to synchronize a 'disable' attribute from on-premises and set it for inactive users.
Why it's wrong here
Entra Connect is for synchronization, not for detecting inactivity.
✓
Configure the 'User sign-in frequency' setting in the 'User feature' settings to automatically remove users inactive for 90 days.
Why this is correct
This built-in feature disables users who haven't signed in for the specified period.

✗
Write a PowerShell script using Microsoft Graph API to check last sign-in times and disable users.
Why it's wrong here
This is not a built-in feature; it requires custom scripting.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the 'User sign-in frequency' setting with session lifetime controls in Conditional Access, or assume that only custom scripting (PowerShell or Power Automate) can handle inactivity-based revocation, missing the fact that Entra ID has a native, built-in feature for this exact purpose.
Detailed technical explanation
How to think about this question
The 'User sign-in frequency' setting is part of Entra ID's Conditional Access policies, but when used under 'User feature' settings, it can enforce a maximum time between sign-ins for all users. Under the hood, Entra ID tracks the 'lastSignInDateTime' property for each user; when this period elapses, the user's tokens are invalidated and they must re-authenticate, effectively revoking access. In a real-world scenario with 50,000 users, this avoids the overhead of scanning logs or running scripts, and it works seamlessly with hybrid identities if the sign-in activity is captured in the cloud.

Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
