You need to automatically scale an Azure SQL Database based on workload patterns. Which Azure feature 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
✓
Serverless compute tier
Azure SQL Database's serverless compute tier automatically scales based on workload. Option B is wrong because auto-scaling is not available in provisioned tier without manual intervention. Option C is wrong because Azure Automation with runbooks can perform scaling but is less efficient than serverless. Option D is wrong because Elastic Database Jobs are for multi-database operations, not scaling.
