The answer is Query Store, which you should use to analyze the root cause of a performance issue in Azure SQL Database. Query Store captures historical query execution plans and wait statistics, allowing you to drill down into specific query behavior over time and identify exactly where performance degraded. This is the correct choice because Intelligent Insights provides high-level summaries and automated diagnostics, but it lacks the granular, query-level detail needed for root cause analysis. On the DP-300 exam, this scenario tests your understanding of when to use monitoring tools versus analysis tools—a common trap is picking Intelligent Insights because it sounds proactive, but remember it alerts you to issues, not why they occurred. For a memory tip, think of Query Store as the “detective” that shows you the plan and the wait, while Intelligent Insights is just the “alarm bell.”
DP-300 Practice Question: Monitor, configure, and optimize database resources
This DP-300 practice question tests your understanding of monitor, configure, and optimize database resources. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You are managing an Azure SQL Database that uses Intelligent Insights. You receive an alert that there is a performance issue with a specific query. You need to analyze the root cause. What should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Query Store to review query execution plans and wait statistics
Option A is correct because Query Store captures query performance metrics and allows detailed analysis. Option B is incorrect because Intelligent Insights provides summaries, not detailed query analysis. Option C is incorrect because database-level metrics don't pinpoint queries. Option D is incorrect because Automatic Tuning applies fixes but doesn't analyze root cause.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Intelligent Insights report
Why it's wrong here
Intelligent Insights provides high-level summaries, not detailed query analysis.

Automatic Tuning recommendations
Why it's wrong here
Automatic Tuning applies fixes but does not provide root cause analysis.
✗
Azure Monitor metrics for the database
Why it's wrong here
Metrics show overall resource usage, not specific query details.
✓
Query Store to review query execution plans and wait statistics
Why this is correct
Query Store provides detailed query performance data for root cause analysis.

Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
