Question 20

What are ARM templates?

Answer 20

Using the resource manager templates you can describe the resources you want to use in a declarative JSON format. The benefits is that the entire ARM template is verified before any code is executed to ensure that the resources will be created and connected correctly.
Templates can even execute PowerShell and Bash scripts before or after the resource has been set up.

Question 21

What is Azure Advisor?

Answer 21

Evaluates your Azure resources and makes recommendations to help improve reliability, security and performance, achieve operational excellence and reduce costs. Advisor is designed to help you save time on cloud optimization. The recommendation service includes suggested actions you can take right away, postpone or dismiss.
