- A
Enable the built-in 'Automatic false positive suppression' feature in the Microsoft Defender XDR settings.
Correct: This feature uses Microsoft's intelligence to close false positives.
- B
Configure an automated investigation and response rule for low-severity alerts to automatically close them.
Why wrong: Wrong: That rule is for investigation, not false positive suppression.
- C
Use the Microsoft Defender XDR API to export alerts daily and run a PowerShell script to close low-severity alerts that match a known false positive list.
Why wrong: Wrong: Requires manual effort and script maintenance.
- D
Create a custom detection rule that excludes low-severity alerts from known false positive indicators.
Why wrong: Wrong: Requires manual tuning and may miss new false positives.
Quick Answer
The answer is to enable the built-in 'Automatic false positive suppression' feature in Microsoft Defender XDR settings. This feature leverages Microsoft's threat intelligence to automatically close low-severity false positive alerts with high confidence, directly addressing alert fatigue without manual intervention. It works by analyzing global signals and behavioral patterns to distinguish genuine threats from benign anomalies, ensuring only alerts with a strong probability of being false positives are suppressed. On the MS-102 exam, this scenario tests your understanding of Defender XDR’s out-of-the-box noise reduction capabilities versus custom tuning or suppression rules, which require manual effort and risk closing legitimate alerts. A common trap is confusing this with automatic investigation rules, which focus on remediation actions rather than false positive classification. Memory tip: think "AI auto-close" for high-confidence fakes—let Microsoft’s intelligence do the heavy lifting.
MS-102 Practice Question: Manage security and threats by using Microsoft Defender XDR
This MS-102 practice question tests your understanding of manage security and threats by using microsoft defender xdr. 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.
Your company uses Microsoft Defender XDR and Microsoft 365 E5 licenses. You are the security administrator. The company's incident response team receives hundreds of low-severity alerts daily, causing alert fatigue. You need to reduce noise by automatically closing low-severity alerts that are determined to be false positives by Microsoft's threat intelligence. You want to minimize manual effort and ensure that only alerts with high confidence of being false positives are closed. What should you do?

- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
