SC-200 Perform threat hunting Practice Question
During a threat hunt in Microsoft Sentinel, you find a query that returns a high number of false positives. Which action should you take to refine the hunt?
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
✓
Add additional filters to the query to exclude known benign activity
Adding additional filters to exclude known benign activity directly reduces false positives by narrowing the scope of the query. Option A is wrong because increasing the time range would gather more data, likely increasing false positives. Option B is wrong because creating a scheduled alert rule is for ongoing detection, not for refining an ad-hoc hunt. Option C is wrong because removing columns only changes the displayed fields, not the data matched, so it does not affect false positive counts.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the query time range to gather more data
Why it's wrong here
Increasing the query time range gathers more data, likely including more benign activity, which would increase false positives.
- ✗
Create a scheduled alert rule based on the query
Why it's wrong here
Creating a scheduled alert rule is intended for continuous monitoring and detection, not for refining the current hunt query to reduce false positives.
- ✗
Remove columns from the result set to simplify analysis
Why it's wrong here
Removing columns from the result set only affects the display of data, not the filtering conditions, so it does not reduce false positives.
- ✓
Add additional filters to the query to exclude known benign activity
Why this is correct
Adding additional filters to exclude known benign activity directly reduces false positives by narrowing the query results to only suspicious entries.
