✑ The compute resources allocated to the databases must scale dynamically.
✑ The solution must meet an SLA of 99.99% uptime.
✑ The solution must have reserved capacity.
✑ Compute charges must be minimized.
What should you include in the recommendation?

A. 20 databases on a Microsoft SQL server that runs on an Azure virtual machine in an availability set
B. 20 instances of Azure SQL Database serverless
C. 20 databases on a Microsoft SQL server that runs on an Azure virtual machine
D. an elastic pool that contains 20 Azure SQL databases

orrect Answer: D
Azure SQL Database elastic pools are a simple, cost-effective solution for managing and scaling multiple databases that have varying and unpredictable usage demands. The databases in an elastic pool are on a single server and share a set number of resources at a set price. Elastic pools in Azure SQL Database enable
SaaS developers to optimize the price performance for a group of databases within a prescribed budget while delivering performance elasticity for each database.
