Full question →mediummultiple choiceObjective-mapped
A security operations center (SOC) uses Microsoft Sentinel. The team wants to detect anomalous behavior for a specific user account that typically logs in only during business hours from a known IP range. They create a scheduled analytics rule that queries the SigninLogs table for logins outside that range or outside business hours. To reduce false positives, which of the following configurations should the analyst apply?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Set the alert threshold to 5 occurrences within the query lookback period.
Correct. Alert threshold sets a minimum number of matching events required to generate an alert, reducing noise from single anomalous but benign logins.
B
Distractor review
Enable entity mapping for the user account to correlate with other data sources.
Entity mapping enriches alerts with additional context but does not directly reduce false positives by filtering low-occurrence events.
C
Distractor review
Increase the query scheduling frequency to every 5 minutes from every hour.
Running the query more frequently increases load and potential duplicates but does not inherently reduce false positives.
D
Distractor review
Group all events into a single alert and set the suppression limit to 1 hour.
Event grouping affects alert aggregation, not the threshold for generating an alert. Suppression after an alert is created might hide subsequent true positives.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this SC-200 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Set the alert threshold to 5 occurrences within the query lookback period. — To reduce false positives in anomaly detection, you can use threshold and alert grouping. The 'Alert threshold' allows setting a minimum number of events per time window before an alert is fired, which helps ignore isolated anomalies. Entity mapping enriches alerts but does not reduce false positives. Event grouping and scheduling frequency control how alerts are aggregated, but the threshold directly filters out low-occurrence events.
