SC-200 Manage a security operations environment Practice Question
Your organization uses Microsoft Defender XDR. You want to ensure that all incidents with severity 'High' are automatically assigned to the 'Tier1' group and have a playbook executed. What should you use?
⚠ Common exam trap
It's easy for candidates to confuse playbooks with automation rules, thinking playbooks alone can handle assignment and triggering, but playbooks are just the action component and require an automation rule to define the trigger and assignment logic.

Correct answer & explanation
✓
Automation rules in Microsoft Sentinel
Automation rules in Microsoft Sentinel allow you to automatically assign incidents to a specific group (e.g., 'Tier1') and trigger a playbook based on incident properties such as severity. This directly meets the requirement to assign 'High' severity incidents to the 'Tier1' group and execute a playbook without manual intervention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Microsoft Defender XDR incident assignment manually by analysts
Why it's wrong here
Manually assigning Microsoft Defender XDR incidents by analysts is a reactive, human-driven process that requires someone to monitor the incident queue and decide ownership. It does not provide automated, consistent assignment based on predefined criteria, which fails the requirement to automate incident assignment at scale. Manual assignment also introduces latency and depends on analyst availability, making it unsuitable for an automated workflow.
- ✗
Custom analytics rules in Microsoft Sentinel
Why it's wrong here
Custom analytics rules in Microsoft Sentinel are detection queries that generate alerts based on data patterns or threshold conditions. While they create incidents, they do not have the ability to assign those incidents to an owner or perform any incident-level management actions. Their scope is limited to alert generation, so they cannot fulfill the requirement to automate assignment.
- ✓
Automation rules in Microsoft Sentinel
Why this is correct
Automation rules in Microsoft Sentinel are the correct mechanism because they are designed to trigger automatically when an incident is created. They can perform actions such as assigning the incident to a specific owner or group, modifying severity, adding tags, or invoking a playbook, all without manual intervention. These rules provide consistent, policy-based incident assignment directly within the Sentinel incident lifecycle.
- ✗
Playbooks in Microsoft Sentinel
Why it's wrong here
Playbooks in Microsoft Sentinel are collections of actions that can be executed within a workflow, but they do not trigger on their own. A playbook must be invoked by an automation rule or directly from an alert, meaning it is not the primary control for incident assignment. While a playbook could contain logic to assign an incident, the automation rule is what defines the trigger and initiates that workflow, making the rule the essential component.
