SC-200 Mitigate threats using Microsoft Sentinel Practice Question
This SC-200 practice question tests your understanding of mitigate threats using microsoft sentinel. 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 wants to quickly check the number of incidents created in Microsoft Sentinel in the last 7 days, grouped by severity. Which KQL query should the analyst use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SecurityIncident | where TimeGenerated > ago(7d) | summarize count() by Severity
Option A is correct because the SecurityIncident table in Microsoft Sentinel stores incident records, and the query filters for incidents created in the last 7 days using `where TimeGenerated > ago(7d)`, then groups them by severity with `summarize count() by Severity`. This directly answers the analyst's need to check the number of incidents grouped by severity.
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.
✓
SecurityIncident | where TimeGenerated > ago(7d) | summarize count() by Severity
Why this is correct
Correct. This query filters incidents from the last 7 days and counts them per severity.

Read the scenario before looking for a memorised answer.
✗
SecurityAlert | where TimeGenerated > ago(7d) | summarize count() by Severity
Why it's wrong here
SecurityAlert contains alert entities, not incidents. Incidents are composed of alerts but are stored in the SecurityIncident table.
✗
SigninLogs | where TimeGenerated > ago(7d) | summarize count() by Status
Why it's wrong here
SigninLogs is for authentication events and does not contain incident data.
✗
DeviceEvents | where TimeGenerated > ago(7d) | summarize count() by ActionType
Why it's wrong here
DeviceEvents tracks endpoint activities and is not related to Sentinel incidents.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing the SecurityIncident table (for incidents) with the SecurityAlert table (for alerts), as many candidates mistakenly use SecurityAlert when the question explicitly asks for incident counts.
Detailed technical explanation
How to think about this question
In Microsoft Sentinel, incidents are created from alerts and other data sources via analytics rules, and the SecurityIncident table is a built-in table that stores these incidents with properties like TimeGenerated (when the incident was created) and Severity (High, Medium, Low, Informational). The `ago(7d)` function uses the UTC timestamp to filter records from the last 7 days, and `summarize count() by Severity` aggregates the count per severity level, which is efficient for quick dashboard-style checks in the Log Analytics workspace.
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.
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
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.
