HashiCorp Terraform-Associate-003 - HashiCorp Certified: Terraform Associate (003) (HCTA0-003)

This is how you specify a module’s version when publishing it to the public Terraform Module Registry, as it uses the tags from your version control system (such as GitHub or GitLab) to identify module versions. You need to use semantic versioning for your tags, such as v1.0.0.

C (✅Correct)– InHCP Terraform, you can use the terraform_remote_state data source to referenceanother workspace's state. This feature isnot available in Terraform CLI.

A (❌Incorrect)– terraform plan (dry runs)is available in both Terraform CLI and HCP Terraform.

B (❌Incorrect)– Secure variable storageexists in HCP Terraform, but CLI users can store variables securely using environment variables or .tfvars files.

D (❌Incorrect)– BothTerraform CLI and HCP Terraform support multiple cloud providers.

From the official Terraform Type Constraints Documentation:

The object({ name = string, age = number }) type expects:

name to be aquoted string, e.g. "John"

age to be anumber, e.g. 52

Option Bsatisfies both:

{

name = "John" #✅Valid string

age = 52 #✅Valid number

}

Let's analyze the incorrect ones:

❌Option A: "fifty two" is not a valid number.

❌Option C: John is unquoted (invalid string), and "fifty two" is not a number.

❌Option D: name = John is not quoted, making it an invalid string in HCL.

Terraform is strict about type and formatting. Stringsmust be quoted, and numbersmust be numeric literals.

Some backends support state locking, which prevents other users from modifying the state file while a Terraform operation is in progress. This prevents conflicts and data loss. Not all backends support this feature, and you can check the documentation for each backend type to see if it does.

These are features of Terraform Cloud, which is a hosted service that provides a web-based UI, remote state storage, remote operations, collaboration features, and more for managing your Terraform infrastructure.

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.

Inrefresh-only mode(terraform apply -refresh-only), Terraformupdates the state fileto match the actual infrastructurewithout modifying resources.

A (Terraform configuration)–Not modifiedin refresh-only mode.

B (Terraform plan)–Plan is generated but not modified.

D (Cloud infrastructure)–Not modifiedin refresh-only mode.

Refresh-Only Mode

The terraform import command is not part of any other Terraform workflow. It must be explicitly invoked by the user with the appropriate arguments, such as the resource address and the ID of the existing infrastructure to import. References = [Importing Infrastructure]

This is the Terraform style convention for indenting a nesting level compared to the one above it. The other options are not consistent with the Terraform style guide.
