DP-300 Practice Question: Monitor, configure, and optimize database resources
You need to monitor Azure SQL Database performance over time and receive alerts when CPU usage exceeds 80%. Which Azure service should you use?
⚠ Common exam trap
A common mix-up: candidates confuse Query Performance Insight (which shows historical query performance data) with a monitoring/alerting tool, but it lacks the ability to set proactive threshold-based alerts like Azure Monitor Alerts provides.

Correct answer & explanation
✓
Azure Monitor Alerts
Azure Monitor Alerts is the correct service because it allows you to create metric-based alert rules that trigger when the CPU percentage of an Azure SQL Database exceeds a defined threshold (e.g., 80%). It continuously monitors performance metrics over time and sends notifications (e.g., email, SMS, or webhook) when the condition is met, fulfilling the requirement for both monitoring and alerting.
