Show Suggested Answer

Suggested Answer: A

To ensure that all queries executed against dbl are captured in the Query Store, you need to enable the Query Store feature for the database and set the query capture mode to ALL.The Query Store feature provides you with insight on query plan choice and performance for Azure SQL Database1.The query capture mode controls whether all queries or only a subset of queries are tracked2.

Here are the steps to enable the Query Store and set the query capture mode to ALL for the database dbl:

Using the Azure portal:

Go to the Azure portal and select your Azure SQL Database server.

Select the database dbl and click onQuery Performance Insightin the left menu.

Click onConfigure Query Storeand turn on theQuery Storeswitch.

In theQuery Capture Modedropdown, selectAlland click onSave.

Using Transact-SQL statements:

Connect to the Azure SQL Database server and the database dbl using SQL Server Management Studio or Azure Data Studio.

Run the following command to enable the Query Store for the database:ALTER DATABASE dbl SET QUERY_STORE = ON;

Run the following command to set the query capture mode to ALL for the database:ALTER DATABASE dbl SET QUERY_STORE (QUERY_CAPTURE_MODE = ALL);

These are the steps to ensure that all queries executed against dbl are captured in the Query Store.

I feel like there was a similar question in our last mock exam, and I think it involved checking the Query Store status after enabling it.

I remember a practice question where we had to configure the Query Store settings, so I think we might need to set the capture mode as well.

This seems straightforward enough. I'd just need to make sure the Query Store is properly configured and enabled to capture all the queries against the dbl database.

Okay, let me think this through. I'd probably start by checking the current Query Store settings to see if it's already enabled. If not, I'll need to figure out how to turn it on and make sure it's capturing all the queries.
