HashiCorp Updated Terraform-Associate-004 Exam Questions and Answers by inayah

When you use a remote backend that needs authentication, HashiCorp recommends that you:

Rationale for Correct Answer: Marking a variable (or output) as sensitive = true primarily prevents Terraform from displaying the value in CLI output and in some UI contexts. It does not prevent the value from being stored in the state file if that value is used by resources. Terraform state must often store attribute values to track and manage infrastructure; sensitive marking is about redaction, not state omission.

Analysis of Incorrect Options (Distractors):

A (True): Incorrect—sensitive values can still be written to state; you must protect state storage (encryption, access control) and avoid storing secrets in state where possible.

Key Concept: Sensitive values are redacted in output, but still can exist in state.

Before using a remote backend in Terraform, it is mandatory to run terraform init. This command initializes a Terraform working directory, which includes configuring the backend. If a remote backend is specified, terraform init will set up the working directory to use it, including copying any existing state to the remote backend if necessary.References = This principle is a fundamental part of workingwith Terraform and its backends, as outlined in general Terraform documentation and best practices. The specific HashiCorp Terraform Associate (003) study materials in the provided files did not include direct references to this information.

This is a secure way to inject sensitive variables into your Terraform run, as they will not be stored in any file or source code repository. You can also use environment variables or variable files with encryption to pass sensitive variables to Terraform.
