AZ-500 Practice Question: Secure Azure using Microsoft Defender for Cloud and Microsoft Sentinel
You manage security for a company using Microsoft Sentinel. The security team wants to automatically assign incidents to the on-call analyst based on the incident severity and the entity involved. They also want to ensure that when an incident is updated, the assignment is re-evaluated. You need to configure this with minimal administrative effort. What should you use?
⚠ Common exam trap
The trap here is assuming that playbooks are required for any automation in Microsoft Sentinel, when automation rules are specifically designed for incident management tasks like assignment and can trigger on updates.
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 and update, with conditions based on severity and entity, and an action to assign the incident to the on-call analyst.
Automation rules in Microsoft Sentinel are the native mechanism for incident management, allowing automatic assignment based on conditions such as severity and entities. They can trigger on both incident creation and update, ensuring re-evaluation when incidents change. This approach requires minimal effort because it is built into the platform and does not require custom playbook development.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure the analytics rule to include the owner in the incident details, and use a scheduled query to update the owner periodically.
Why it's wrong here
Analytics rules do not support setting the incident owner directly; they only generate incidents. A scheduled query could update incidents, but it would require custom logic and would not be event-driven, leading to delays and increased complexity. This approach does not meet the requirement for automatic assignment on creation and update.
- ✗
Create a playbook that uses the Microsoft Sentinel connector to assign the incident, and configure the analytics rule to run the playbook on incident creation.
Why it's wrong here
Playbooks are built on Azure Logic Apps and are intended for more complex orchestration, often involving external systems. While they can assign incidents, they are not automatically triggered on incident updates unless explicitly configured, and they require more administrative effort to create and maintain than automation rules.
- ✓
Create an automation rule that triggers on incident creation and update, with conditions based on severity and entity, and an action to assign the incident to the on-call analyst.
Why this is correct
Automation rules in Microsoft Sentinel are designed to handle incident management tasks such as assignment, tagging, and status changes. They can trigger on incident creation and update, and support conditions based on analytics rule name, severity, and entities. This meets the requirement with minimal effort, as no custom logic or playbooks are needed.
- ✗
Use Microsoft Defender for Cloud's workflow automation to assign the incident to the on-call analyst based on severity.
Why it's wrong here
Microsoft Defender for Cloud workflow automation triggers on alerts and can perform actions like assigning owners, but it operates on Defender for Cloud alerts, not on Microsoft Sentinel incidents. The scenario specifically involves Microsoft Sentinel incidents, and Defender for Cloud does not manage Sentinel incident assignment or updates.
