This SC-100 practice question tests your understanding of evaluate grc and security operations strategies. 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.
A company's security team wants to automate response to common incidents like malware detected on endpoints. They have Microsoft 365 Defender and Microsoft Sentinel. Which feature should they use to create automated playbooks?
Microsoft Purview's data loss prevention policies
Why wrong: Focuses on data protection, not incident response.
Microsoft Sentinel automation rules and playbooks
Integrates with Logic Apps for automated response to incidents.
Azure Policy
Why wrong: Enforces resource configurations, not incident response.
Microsoft Defender for Cloud's workflow automation
Why wrong: Used for cloud resources, not endpoint incidents.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Microsoft Sentinel automation rules and playbooks
Microsoft Sentinel's automation rules and playbooks are the correct choice because they are specifically designed to automate incident response by triggering predefined actions (e.g., running a Logic App) when a detection event, such as malware on an endpoint, is ingested from Microsoft 365 Defender. This integration allows security teams to create custom, automated workflows that respond to common incidents without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often confuse Microsoft Defender for Cloud's workflow automation (which can send notifications or trigger a Logic App for Defender for Cloud alerts) with Sentinel's full playbook engine, but Sentinel is the correct choice because it is the centralized SIEM/SOAR platform that ingests alerts from Microsoft 365 Defender and orchestrates complex, multi-step automated responses across the entire security ecosystem.
Detailed technical explanation
Under the hood, Sentinel automation rules evaluate conditions (e.g., alert severity, entity type) and then invoke a playbook, which is an Azure Logic App that can execute hundreds of connectors—such as Microsoft Graph API to isolate a device, ServiceNow to create a ticket, or Teams to notify analysts. A subtle behavior is that playbooks can be triggered automatically from an automation rule or manually from an incident, and they support synchronous execution (waiting for completion) or asynchronous fire-and-forget, which is critical for time-sensitive responses like endpoint isolation.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
