Which of the following statements about local modules is incorrect:
Correct Answer:C
Version constraints are supported only for modules installed from a module registry, such as the public Terraform Registry or Terraform Cloud's private module registry. Other module sources can provide their own versioning mechanisms within the source string itself, or might not support versions at all. In particular, modules sourced from local file paths do not support version; since they're loaded from the same source repository, they always share the same version as their caller.

After creating a new workspace "PROD" you need to run the command terraform select PROD to switch to it.
Correct Answer:A
By default, when you create a new workspace you are automatically switched to it
To create a new workspace and switch to it, you can use terraform workspace new
Example:
$ terraform workspace new example
Created and switched to workspace "example"!
You're now on a new, empty workspace. Workspaces isolate their state, so if you run "terraform plan" Terraform will not see any existing state for this configuration.
