Applying the software development principle of DRY (Don't Repeat Yourself) is considered a best practice when using Terraform. For example, multiple instances of the same resource can be created using the for_each or count meta-arguments.

In this lab, you will refactor a Terraform template to use dynamic blocks. You will also learn how dynamic blocks differ from Terraform meta-arguments.
Upon completion of this intermediate-level lab, you will be able to:
