Actual exam question for Microsoft's DP-300 exam

Question #: 114
Topic #: 5

[All DP-300 Questions]

You have an Azure SQL database named sqldb1.

You need to minimize the possibility of Query Store transitioning to a read-only state.

What should you do?

AHalve the value of Data Flush Interval.

BDouble the value of Statistics Collection Interval.

CHalve the value of Statistics Collection Interval.

DDouble the value of Data Flush Interval.

Show Suggested Answer

Suggested Answer: B

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.

I vaguely remember that increasing the Data Flush Interval could lead to issues, so maybe doubling it isn't the best option?

I feel like halving the Statistics Collection Interval might help, but I’m not entirely confident about how that impacts the Query Store.

I think I practiced a question where adjusting the Statistics Collection Interval helped with performance, but I can't recall if doubling or halving was better.

I remember something about the Data Flush Interval affecting how often data is written to the Query Store, but I'm not sure if halving it is the right move.
