The correct answer is to count alerts by severity over the last week. This KQL query in Microsoft Sentinel uses the `summarize` operator with `count()` on the `AlertSeverity` field, then filters results to the last 7 days using `where TimeGenerated > ago(7d)`, and finally orders the output by severity descending. On the SC-200 exam, this pattern tests your ability to distinguish between alert aggregation and incident analysis—a common trap is confusing `AlertSeverity` with `IncidentSeverity` or assuming the query hunts for a single threat. The query’s purpose is purely statistical: it provides a severity breakdown of all alerts generated in the past week, not a deep investigation. Memory tip: think “7 days, count, and sort down”—if you see `ago(7d)` with `summarize count()` by severity, you are always counting alerts over the last week.

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.
