Explanation:
The Max Size (MB) limit isn't strictly enforced. Storage size is checked only when Query Store writes data to
disk. This interval is set by the Data Flush Interval (Minutes) option. If Query Store has breached the maximum
size limit between storage size checks, it transitions to read-only mode.
Incorrect Answers:
C: Statistics Collection Interval: Defines the level of granularity for the collected runtime statistic, expressed in
minutes. The default is 60 minutes. Consider using a lower value if you require finer granularity or less time to
detect and mitigate issues. Keep in mind that the value directly affects the size of Query Store data.

Explanation:
The Query Store feature in Azure Database for MySQL provides a way to track query performance over time.
Query Store simplifies performance troubleshooting by helping you quickly find the longest running and most
resource-intensive queries. Query Store automatically captures a history of queries and runtime statistics, and it
retains them for your review. It separates data by time windows so that you can see database usage patterns.
Data for all users, databases, and queries is stored in the mysql schema database in the Azure Database for
MySQL instance.

-- and that Francois Ajenstat is a valid operator name.
USE msdb ;
GO
EXEC dbo.sp_add_notification
@alert_name = N'Test Alert',
@operator_name = N'Francois Ajenstat',
@notification_method = 1 ;
GO
