HashiCorp Terraform Associate Exam Practice Questions (P. 3)

GPT-4o - Answer

Implementing a provisioning pipeline, as described in option D, is the most effective method to solve the inconsistency issue in configuring compute instances. This approach allows for automated, uniform configuration management across all instances through the use of infrastructure as code principles. Using a version control system to manage infrastructure code ensures that any deployments are consistent, reproducible, and can be easily rolled back if issues occur. Moreover, adding code reviews introduces an extra layer of validation, enhancing the reliability and stability of the deployed infrastructure.

The correct understanding here revolves around the function of the 'terraform init' command. It does not create nor initialize a sample main.tf file but rather prepares the working directory for use by initializing the backend, installing required provider plugins, and setting up the necessary environment to manage the infrastructure. The existence of a main.tf file or any .tf files is a prerequisite, and if absent, leads to warnings about the lack of configuration files, not their automatic creation.

Terraform supports a range of sources for importing modules, including local paths, Git repositories, and official module registries. However, there's no support for importing modules directly from FTP servers. This limitation is important to keep in mind when planning module management and sourcing in your Terraform configurations.

Absolutely right, secure variable storage is the unique feature of Terraform Enterprise and Terraform Cloud that isn't found in the Terraform CLI. This feature provides essential security for sensitive data by encrypting and protecting variables like passwords and API keys. It's a game-changer because it avoids the risk of exposing such critical information in plain text, ensuring that your infrastructure remains secure and compliant.
