Terraform-Associate-004 HashiCorp Certified: Terraform Associate (004) (HCTA0-004) Free Practice Exam Questions (2026 Updated)

Terraform state files are not automatically encrypted by default. Sensitive values are stored in plaintext within the state file. However, you can protect the state file by using remote backends that support encryption, such as AWS S3 with server-side encryption enabled or Terraform Cloud, which offers encrypted state storage.

The command that makes your code more human readable is terraform fmt. This command is used to rewrite Terraform configuration files to a canonical format and style, following the Terraform language style conventions and other minor adjustments for readability. The command is optional, opinionated, and has no customization options, but it is recommended to ensure consistency of style across different Terraform codebases. Consistency can help your team understand the code more quickly and easily, making the use of terraform fmt very important. You can run this command on your configuration files before committing them to source control or as part of your CI/CD pipeline. References = : Command: fmt : Using Terraform fmt Command to Format Your Terraform Code

Rationale for Correct Answer: terraform plan -destroy does not destroy anything. It only creates a plan that proposes destroying all managed resources. Actual destruction happens only when you run terraform destroy or terraform apply with an approved destroy plan.

Analysis of Incorrect Options (Distractors):

A: Does trigger destruction (interactive approval by default).

B: Incorrect because terraform plan -destroy does not perform destruction.

D: Does trigger destruction and skips the interactive approval prompt.

Key Concept: Difference between planning a destroy and executing a destroy.

C (✅Correct)– If changes require aresource replacement(e.g., changing an immutable attribute like instance type), Terraform willdestroy and recreate the resource.

E (✅Correct)– Terraform only appliesthe configuration in the current directory or workspace.

Detailed Explanation:

Rationale for Correct Answer: Terraform logging is enabled by setting the TF_LOG environment variable. Common values include TRACE, DEBUG, INFO, WARN, and ERROR. For example: export TF_LOG=DEBUG.

Analysis of Incorrect Options (Distractors):

A. Set the log level command-line flag. Incorrect. Terraform does not use a general CLI flag for verbose log level control.

C. Set the log level in your terraform block. Incorrect. Logging is not configured in the Terraform configuration block.

Key Concept: Terraform troubleshooting logs are controlled through environment variables.

You do not need to use different Terraform commands depending on the cloud provider you use. Terraform commands are consistent across different providers, as they operate on the Terraform configuration files and state files, not on the provider APIs directly.

From Terraform CLI Overview:

" Terraform provides a consistent CLI workflow regardless of which cloud or service you’re managing. "

Thesame Terraform commandswork across all providers via plugins.
