How does Terraform find the root module?

Terraform looks in the current working directory where you run the commands. This directory is the root module.

intermediate

Can the root module call other modules?

Yes, the root module can include other modules to organize and reuse infrastructure code.

beginner

Why is the root module important in Terraform?

It acts like the main blueprint for your infrastructure. All Terraform commands start here, and it controls how other modules fit together.

beginner

What files are typically found in the root module?

Files like main.tf, variables.tf, outputs.tf, and terraform.tfstate are usually in the root module folder.

Where does Terraform look for the root module?

A In the current working directory

B In the cloud provider's console

C In a hidden system folder

D In the user's home directory

Terraform uses the current working directory as the root module location.

What is the main role of the root module?

A To define the main infrastructure configuration

B To store Terraform state files only

C To manage cloud provider credentials

D To run Terraform commands remotely

The root module defines the main infrastructure setup and configuration.

Can the root module include other modules?

A Only if they are in the same folder

B No, modules are separate and cannot be linked

C Yes, to organize and reuse code

D Only if they are from the Terraform registry

The root module can call other modules to organize and reuse infrastructure code.

Which file is NOT typically part of the root module?

A main.tf

B index.html

C variables.tf

D outputs.tf

index.html is not related to Terraform configuration files.

What happens if you run Terraform commands outside the root module directory?

A Terraform will automatically find the root module elsewhere

B Terraform will run but ignore all modules

C Terraform will create a new root module automatically

D Terraform will fail because it can't find configuration files

Terraform needs to run in the root module directory to find configuration files.

Explain what the root module is and why it is important in Terraform.

Think of the root module as the main folder where Terraform looks first.

Describe how the root module interacts with other modules in a Terraform project.
