DP-300 Practice Question: Monitor, configure, and optimize database resources
You need to monitor the storage space usage of an Azure SQL Database over time. Which tool should you use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure SQL Analytics (Azure Monitor)
Azure SQL Analytics in Azure Monitor provides historical storage metrics. Option A is wrong because Intelligent Insights is for proactive diagnostics, not storage monitoring. Option C is wrong because Query Store focuses on query performance. Option D is wrong because SSMS does not provide historical monitoring.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Intelligent Insights
Why it's wrong here
Intelligent Insights analyses performance regressions and detects anomalies in query execution, not storage consumption trends. It would be the right choice when diagnosing sudden performance degradation, such as a query plan regression causing elevated DTU usage.
- ✓
Azure SQL Analytics (Azure Monitor)
Why this is correct
Azure SQL Analytics consumes the database's resource-usage telemetry, including storage consumption, and surfaces it in Azure Monitor with historical trending. This satisfies the requirement to track storage space usage over time rather than only viewing a current value.
- ✗
Query Store
Why it's wrong here
Query Store captures query plans, runtime statistics and regressions, not database storage metrics over time. It is the correct tool when investigating why a specific query's performance changed after a plan change or index modification.
- ✗
SQL Server Management Studio (SSMS)
Why it's wrong here
SSMS is a client administration tool; it displays current database size but does not retain historical storage usage trends. It would be suitable for ad-hoc tasks like running T-SQL queries or scripting index maintenance, not continuous metric monitoring.
