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
✓
Use the Query Store reports in the Azure portal
Query Store in Azure SQL Database provides built-in reports to identify top resource-consuming queries by CPU, IO, and duration, making it the easiest and most direct method. Option B (SQL Server Profiler) is not supported in Azure SQL Database. Option C (Extended Events) is more complex and not the simplest approach for this task. Option D (sys.dm_exec_query_stats) can be used but lacks persistent historical data and is more effort than using Query Store reports.
