The terraform import command allows Terraform to takeexistinginfrastructure andbring it under Terraform’s management.

A (terraform get)is incorrect because it is used to fetch modules.

B (terraform refresh)is incorrect because it only updates Terraform's state to match the infrastructure but does not import resources.

D (terraform init)is incorrect because it only initializes the Terraform working directory.

You can install third party plugins using terraform init, as long as you specify the plugin directory in your configuration or as a command-line argument. You can also use the terraform providers mirror command to create a local mirror of providers from any source.

Detailed Explanation:

Rationale for Correct Answer (True):Variables without defaults are required inputs. If the calling module doesn’t supply a value, Terraform will fail with an error at plan time.

Analysis of Incorrect Option:

False: Incorrect, because Terraform does not assume defaults when none are provided.

Key Concept:Terraform modules enforce required vs. optional variables depending on whether a default is set.

If you update the version constraint in your Terraform configuration, Terraform will update your lock file the next time you run terraform init3. This will ensure that you use the same provider versions across different machines and runs.

The terraform state list command lists all resources that are managed by Terraform in the current state file1. The terraform state show command shows the attributes of a single resource in the state file2. By using these two commands, you can compare the VM IDs in your list with the ones in the state file and identify which one is managed by Terraform.

However, itdoes notcheck if resource configurations are valid with the provider.

This is not a valid backend for Terraform, as it does not support locking or versioning of state files4. The other options are valid backends that can store state files in a central location.

This is the workflow for deploying new infrastructure with Terraform, as it will create a plan and apply it to the target environment. The other options are either incorrect or incomplete.

The public Terraform Module Registry is free to use, as it is a public service that hosts thousands of self-contained packages called modules that are used to provision infrastructure. You can browse, use, and publish modules to the registry without any cost.

Terraform allows usingprivate module sourceshosted in:

C (Internally hosted VCS platforms, e.g., GitLab, Bitbucket, GitHub Enterprise)✅

D (Private GitHub repositories)✅

A (Public GitHub repository)❌–GitHubis supported, but apublic repo is not "private".

B (Public Terraform Registry)❌–The public registryis not a private source.
