HashiCorp Terraform Associate (004) Question 59
Single answer3b Initialize a Terraform working directoryA DevOps engineer clones a Terraform configuration that uses an S3 backend for remote state and declares the AWS provider with a version constraint. The engineer has not worked in this directory before and wants Terraform to download the required provider plugins and configure the backend before running a plan. Which command should the engineer run first in this working directory?
- A
terraform init
- B
terraform validate
- C
terraform refresh
- D
terraform fmt
Show answer and explanation
Correct answer: A
Explanation
The correct answer is terraform init because initialization is the required first step when using a Terraform configuration in a new or changed working directory. According to Terraform CLI workflow and command documentation, terraform init performs several setup tasks, including initializing the backend, downloading and installing provider plugins, and preparing modules if they are referenced. This is especially important when the configuration uses a remote backend such as S3, because Terraform must configure backend access before it can read or write state remotely. A common misconception is that terraform validate can prepare the environment, but validation only checks configuration correctness and does not initialize the directory. Similarly, terraform fmt only formats code, and terraform refresh does not replace initialization. Best practice is to run terraform init whenever a directory is first used, when backend settings change, or when provider/module dependencies need to be installed or updated.
- A. Correct.
Correct.
terraform initis the command used to initialize a Terraform working directory. It installs required provider plugins, sets up the configured backend, and prepares the.terraformdirectory so later commands such asterraform plancan run successfully. In this scenario, initialization is required because the engineer is using the directory for the first time and the configuration includes both a backend and provider requirements. - B. Incorrect.
Incorrect.
terraform validatechecks whether the configuration is syntactically valid and internally consistent, but it does not perform full working-directory initialization. While validation is useful after initialization, it does not replaceterraform initfor downloading providers or configuring the backend. - C. Incorrect.
Incorrect.
terraform refreshis not the correct first step for preparing a new working directory. Historically it was used to reconcile state with real infrastructure, but it does not initialize the backend or install providers. In modern workflows, refresh behavior is generally handled during planning and applying rather than as a separate first-time setup step. - D. Incorrect.
Incorrect.
terraform fmtformats Terraform configuration files to a canonical style. It is helpful for readability and consistency, but it does not configure backends, install providers, or otherwise prepare a new working directory for execution.
