- A
Using the 'Event grouping' option under 'Alert grouping' with a 6-hour re-open window
Correct. 'Event grouping' (Group alerts into a single incident if they match criteria) allows you to deduplicate based on user and IP, and the re-open window prevents new incidents for the same combination within the selected time.
- B
Setting a custom query threshold so that alerts are only generated once per time window
Why wrong: Incorrect. 'Alert threshold' in the 'Schedule' section sets how many query results are needed to generate an alert, but it does not deduplicate alerts into a single incident.
- C
Enabling 'Suppression' on the 'Schedule' page to stop running the query after the first incident
Why wrong: Incorrect. 'Suppression' (Stop running query after generating an incident) stops the entire rule from running for a period, which would miss other user/IP combinations.
- D
Using the 'Custom' alert grouping and setting a time window for re-opening
Why wrong: Incorrect. There is no 'Custom' alert grouping option; the choice is between 'Group alerts into a single incident' (Event grouping) and 'Trigger an alert for each event' (Alert grouping).
SC-200 Mitigate threats using Microsoft Sentinel Practice Question
This SC-200 practice question tests your understanding of mitigate threats using microsoft sentinel. 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. A key principle to apply: event grouping consolidates multiple alerts into a single incident.. 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 SOC analyst is configuring a scheduled analytics rule in Microsoft Sentinel that detects sign-ins from IP addresses contained in a custom threat intelligence watchlist. The analyst wants to avoid creating multiple incidents for the same user and source IP address combination within a 6-hour window. Which configuration in the 'Incident creation' settings should the analyst use to achieve this suppression?
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
Using the 'Event grouping' option under 'Alert grouping' with a 6-hour re-open window
Option A is correct because the 'Event grouping' setting under 'Alert grouping' allows the analyst to group alerts that fire within a specified time window into a single incident. By setting the 'Re-open window' to 6 hours, any new alert matching the same user and source IP address combination will not create a new incident but will instead re-open the existing incident, effectively suppressing duplicate incidents within that window.
Key principle: Event grouping consolidates multiple alerts into a single incident.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing 'Suppression' on the Schedule page (which stops the query from running) with 'Event grouping' (which suppresses duplicate incidents while still allowing the query to run and detect new threats).
Detailed technical explanation
How to think about this question
Under the hood, 'Event grouping' uses a 'Re-open window' that starts when the first incident is created; any subsequent alert matching the same grouping key (e.g., user and IP) within that window will re-open the incident rather than create a new one. This is distinct from 'Alert grouping' which only controls how alerts are combined into incidents at creation time. In a real-world scenario, if a user's IP changes within the 6-hour window, a new incident would be created because the grouping key (user + IP) is different, ensuring that only truly duplicate combinations are suppressed.
KKey Concepts to Remember
- Event grouping consolidates multiple alerts into a single incident.
- It uses specified entities (e.g., user, IP) for grouping criteria.
- The re-open window prevents new incidents for the same grouped alerts.
- This setting is found under 'Incident settings' in analytics rules.
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
Event grouping consolidates multiple alerts into a single incident.
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. Event grouping consolidates multiple alerts into a single incident. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
