You have an Azure SQL database. You identify a long running query. You need to identify which operation in the query is causing the performance issue. What should you use to display the query execution plan in Microsoft SQL Server Management Studio (SSMS)?
Correct Answer: A
SQL Server Management Studio provides the ability to view the live execution plan of an active query. This live query plan provides real-time insights into the query execution process as the controls flow from one query plan operator to another. The live query plan displays the overall query progress and operator-level run-time execution statistics such as the number of rows produced, elapsed time, operator progress, etc. Because this data is available in real time without needing to wait for the query to complete, these execution statistics are extremely useful for debugging query performance issues.
