- A
Create a separate analytics rule that triggers on the same alert and uses a playbook to isolate the device.
Why wrong: Analytics rules generate incidents; they don't directly trigger playbooks on alerts.
- B
Use automatic attack disruption in Microsoft Defender XDR to isolate the device automatically.
Why wrong: Attack disruption acts on high-confidence alerts without manual approval.
- C
Configure an automated response in Defender for Endpoint to isolate the device immediately when an alert is generated.
Why wrong: This bypasses SOC confirmation and could cause unnecessary isolation.
- D
Create an automation rule in Microsoft Sentinel that triggers a playbook with an approval step before executing device isolation.
This ensures human confirmation before taking action.
SC-200 Manage a security operations environment Practice Question
This SC-200 practice question tests your understanding of manage a security operations environment. 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 SOC uses Microsoft Sentinel and Microsoft Defender XDR. An incident is created from a Defender for Endpoint alert about a malware detection on a device. The incident has low priority, but you want to automatically isolate the device from the network if the alert is confirmed as a true positive by the SOC. What is the recommended approach?
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 in Microsoft Sentinel that triggers a playbook with an approval step before executing device isolation.
Option D is correct because it aligns with the recommended SOC workflow: an automation rule in Microsoft Sentinel triggers a playbook that includes an approval step, ensuring that device isolation only occurs after the SOC confirms the alert as a true positive. This approach maintains human oversight for low-priority incidents while leveraging automation for the response action.
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 often confuse automated response capabilities (like immediate isolation in Defender for Endpoint) with the need for human approval in a SOC workflow, leading them to choose Option C without considering the 'confirmed as a true positive' requirement.
Detailed technical explanation
How to think about this question
The automation rule in Microsoft Sentinel uses a trigger condition based on the incident's provider (e.g., 'Microsoft Defender for Endpoint') and severity, then invokes a playbook (Azure Logic App) that can include an approval step via Microsoft Teams or email. The playbook uses the 'Isolate device' action from the Microsoft Defender for Endpoint connector, which sends an HTTP POST request to the Defender for Endpoint API (e.g., 'https://api.security.microsoft.com/api/machines/{machineId}/isolate') to initiate network isolation. This ensures that the isolation command is only sent after the SOC analyst explicitly approves the action, preventing unintended network disruption for low-priority incidents.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
