The correct answer is automation rules with a condition to close incidents. In Microsoft Sentinel, automation rules are the native, lightweight feature designed to automatically close incidents based on specific criteria, such as an incident originating from a known test IP address. Unlike playbooks, which require Azure Logic Apps and are better suited for complex, multi-step responses, automation rules run directly within Sentinel and are ideal for reducing alert fatigue by suppressing low-severity incidents without manual effort. On the SC-200 exam, this scenario tests your understanding of when to use automation rules versus playbooks—a common trap is choosing playbooks for simple closure tasks, but remember that automation rules handle conditions natively and are the correct tool for automated incident suppression. Memory tip: think of automation rules as the “if-then” gatekeeper that closes incidents before they ever reach an analyst.
SC-200 Mitigate threats using Microsoft Sentinel Practice Question
This SC-200 practice question tests your understanding of mitigate threats using microsoft sentinel. 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.
A SOC team uses Microsoft Sentinel. They receive a large volume of low-severity incidents from a specific analytics rule that causes alert fatigue. They want to automatically close incidents that match certain criteria (e.g., originating from a known test IP). Which feature should they configure?
Automation rules with a condition to close incidents
Automation rules can be configured with conditions (e.g., if the source IP is in a watchlist) and an action to close the incident, effectively suppressing unwanted alerts.
B
Playbook with a timer trigger
Why wrong: A playbook with a timer trigger runs on a schedule, not in response to incident creation, and is not ideal for closing incidents immediately based on conditions.
C
Watchlist integration
Why wrong: Watchlists store reference data for use in queries and automation, but by themselves do not perform actions like closing incidents.
D
Fusion rule
Why wrong: Fusion rules correlate alerts to detect multistage attacks, not to close low-severity incidents.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Automation rules with a condition to close incidents
Automation rules in Microsoft Sentinel allow you to automatically close incidents based on specific conditions, such as a known test IP address. This directly addresses alert fatigue by suppressing low-severity incidents without manual intervention. Unlike playbooks, automation rules are lightweight and run natively within Sentinel without requiring a Logic Apps instance.
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
Microsoft often tests the distinction between automation rules (native, condition-based actions) and playbooks (external Logic Apps workflows), leading candidates to incorrectly choose a playbook when a simpler automation rule suffices.
Detailed technical explanation
How to think about this question
Automation rules in Sentinel trigger on incident creation or update and can evaluate conditions such as 'Alert Name contains X' or 'Source IP in watchlist Y' using KQL-like expressions. They execute actions like changing status, assigning ownership, or running a playbook, all without incurring additional compute costs. In a real-world scenario, you could combine an automation rule with a watchlist of known test IPs to automatically close incidents, but the rule itself is the feature that performs the closure action.

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 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.
