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.

Ah, the age-old dilemma of to double or to halve. I'm going with D - doubling the value of Data Flush Interval seems like the safest bet to me.

Halving the Data Flush Interval? That's a bold move, but I'm not convinced that's the right solution here. Let's think this through a bit more.

I think Hana has a point, reducing the Statistics Collection Interval could also be effective in minimizing the possibility of Query Store becoming read-only.

Hmm, I'm not so sure. I think C might be the way to go - halving the value of Statistics Collection Interval could be a better approach.

I agree with you, C seems like the best choice - halving the value of Statistics Collection Interval.

But wouldn't doubling the value of Data Flush Interval help prevent Query Store from transitioning to a read-only state?

I think the answer is B. Doubling the value of Statistics Collection Interval will minimize the possibility of Query Store transitioning to a read-only state.
