DP-300 Practice Question: Monitor, configure, and optimize database resources
You are monitoring an Azure SQL Database using Intelligent Insights. The built-in intelligence detects a performance issue and suggests a specific index to create. The database is running the Business Critical service tier. You want to automatically implement this recommendation without manual intervention. What should you configure?

Correct answer & explanation
✓
Enable automatic tuning for 'CREATE INDEX' in the Azure portal.
Azure SQL Database's automatic tuning can automatically implement index recommendations when 'CREATE INDEX' is enabled. Option A is incorrect because 'FORCE LAST GOOD PLAN' is for plan correction, not index creation. Option B is incorrect because Query Store is a monitoring tool, not an automatic tuning feature. Option C is incorrect because Azure Advisor only provides recommendations, not automatic implementation.
