You are designing an Azure development environment. Team members learn Azure development
techniques by training in the development environment.
The development environment must auto scale and load balance additional virtual machine (VM)
instances.
You need to recommend the most cost-effective compute-instance size that allows team members
to work with Azure in the development environment.
What should you recommend?

A.
Azure A1 standard VM Instance

B.
Azure A2 basic VM Instance

C.
Azure A3 basic VM Instance

D.
Azure A9 standard VM Instance

Explanation:
Azure A1 standard VM Instance would be cheapest with 1 CPU core, 0.75 GB RAM, and 40 GB HD. It
would be good enough for training purposes.
