- A
Create an automation rule that triggers on incident creation with severity high, and runs a playbook that uses the 'Update user' action to disable the account.
A playbook with Graph API can disable a user.
- B
Use a scheduled analytics rule that runs every hour and disables accounts found in the results.
Why wrong: Scheduled rules only generate alerts, they don't perform actions.
- C
Configure Microsoft Entra ID to automatically apply a conditional access policy blocking sign-ins when a high-severity alert is raised.
Why wrong: Conditional access policies are not automatically applied based on alerts without custom automation.
- D
Create a playbook that uses the 'Run a query' action to find the device and then uses Microsoft Defender for Endpoint to isolate the device.
Why wrong: This isolates the device, not disables the user account.
Automating User Account Disablement in Microsoft Sentinel
This SC-200 practice question tests your understanding of manage a security operations environment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 Defender XDR and Microsoft Sentinel. You need to configure a solution that automatically blocks a user's account when a high-severity incident is generated. The solution must use built-in capabilities without custom code. What should you do?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create an automation rule that triggers on incident creation with severity high, and runs a playbook that uses the 'Update user' action to disable the account.
Option A is correct because Microsoft Sentinel automation rules can trigger on incident creation with a condition of severity equals high, and then run a playbook. The playbook can use the Microsoft Entra ID connector's 'Update user' action to disable the user account, which is a built-in capability requiring no custom code. This directly meets the requirement to automatically block a user's account when a high-severity incident is generated.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse device isolation (Microsoft Defender for Endpoint) with user account blocking (Microsoft Entra ID), or incorrectly assume that conditional access policies can be triggered by external alerts, when in fact they require specific risk signals from Microsoft Entra ID Protection.
Detailed technical explanation
How to think about this question
Under the hood, the automation rule in Microsoft Sentinel uses a trigger condition that evaluates the incident's properties, such as severity, and then invokes a playbook via Azure Logic Apps. The 'Update user' action in the Microsoft Entra ID connector sends a PATCH request to the Microsoft Graph API endpoint `/users/{id}` with the `accountEnabled` property set to `false`, which immediately disables the user's sign-in across all Microsoft services. This integration is native and requires no custom scripting, relying on prebuilt connectors and OAuth 2.0 authentication managed by the Logic Apps managed identity.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
