The answer is to add allowlist conditions that exclude known administrative tools. This approach directly reduces false positives in hunting queries by filtering out benign activity that mimics lateral movement, such as legitimate remote management traffic, without altering the core detection logic. On the Microsoft Security Operations Analyst SC-200 exam, this concept tests your ability to balance precision and coverage in Kusto Query Language (KQL) threat hunting—a common trap is to widen time ranges or raise thresholds, which can miss true positives, or to switch to less sensitive data sources, which sacrifices detection depth. Remember that allowlisting is a surgical refinement: it preserves the query’s intent while silencing noise from expected administrative behavior. A useful memory tip is “allowlist, don’t amputate”—exclude the known good rather than weaken the detection.
SC-200 Perform threat hunting Practice Question
This SC-200 practice question tests your understanding of perform threat hunting. 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 security analyst is reviewing a threat hunting query in Microsoft Sentinel that uses the Kusto Query Language (KQL) to identify potential lateral movement. The query returns a large number of false positives. What is the most effective way to reduce false positives while maintaining detection coverage?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add allowlist conditions to exclude known administrative tools.
Option B is correct because adding allowlist conditions, such as excluding known administrative tools or approved remote management traffic, directly reduces false positives without removing the core logic. Option A is wrong because reducing the time range may miss true positives. Option C is wrong because the question asks to maintain detection coverage, and using a less sensitive data source would reduce coverage. Option D is wrong because increasing the threshold may also miss true positives.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 threshold for the anomaly score in the query.
Why it's wrong here
Increasing the threshold might cause true positives to be missed.
✓
Add allowlist conditions to exclude known administrative tools.
Why this is correct
Allowlisting known safe tools reduces false positives while keeping the detection logic intact.

Read the scenario before looking for a memorised answer.
✗
Reduce the time range of the query to the last 1 hour.
Why it's wrong here
Reducing the time range may miss true positives that occur outside that window.
✗
Replace the query with a different data source that has less noise.
Why it's wrong here
Changing the data source may reduce detection coverage.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
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.
