- A
Use Microsoft Sentinel bookmarks to mark the alerts as false positives.
Why wrong: Bookmarks are for preserving evidence, not for automated suppression.
- B
Configure an automated investigation and remediation rule in Microsoft Defender XDR to suppress alerts matching the legacy application pattern.
Automated investigation rules can suppress false positives based on conditions.
- C
Create a watchlist in Microsoft Sentinel containing the legacy application's user accounts and use it in the rule.
Why wrong: Watchlists are for correlation, not suppression of alerts.
- D
Modify the analytics rule in Microsoft Sentinel to exclude the legacy application IP range.
Why wrong: This would affect all detections, not just false positives, and is harder to maintain.

SC-200 Manage a security operations environment Practice Question
This SC-200 practice question tests your understanding of manage a security operations environment. 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.
Your organization uses Microsoft Defender XDR and Microsoft Sentinel. The security operations center (SOC) team frequently receives false positive alerts for a specific user login pattern from a legacy application. You need to reduce alert fatigue without disabling the underlying detection rule. What should you configure?
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
✓
Configure an automated investigation and remediation rule in Microsoft Defender XDR to suppress alerts matching the legacy application pattern.
Option B is correct because configuring an automated investigation and remediation rule in Microsoft Defender XDR allows you to suppress alerts that match a specific pattern (e.g., legacy application login behavior) without disabling the underlying detection rule. This directly reduces alert fatigue by automatically closing or ignoring false positive alerts while keeping the rule active for genuine threats.
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 modifying the detection rule (options C or D) with configuring a separate suppression or response mechanism, failing to realize that automated investigation and remediation rules in Defender XDR can suppress alerts without altering the original detection logic.
Detailed technical explanation
How to think about this question
Automated investigation and remediation rules in Microsoft Defender XDR use playbooks or built-in actions to automatically respond to alerts based on conditions like entity type, severity, or custom patterns. Under the hood, these rules can trigger suppression actions that close alerts without affecting the detection rule's ability to generate future alerts for other patterns. In a real-world scenario, a SOC team might use this to suppress alerts from a legacy VPN gateway that generates repeated false positives due to non-standard authentication protocols, while still alerting on anomalous logins from the same gateway.
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 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.
