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

You should run terraform fmt to rewrite all Terraform configurations within the current working directory to conform to Terraform-style conventions. This command applies a subset of the Terraform language style conventions, along with other minor adjustments for readability. It is recommended to use this command to ensure consistency of style across different Terraform codebases. The command is optional, opinionated, and has no customization options, but it can help you and your team understand the code more quickly and easily. References = : Command: fmt : Using Terraform fmt Command to Format Your Terraform Code

Sensitive values such as API tokens should be stored in a secure way, either in Terraform Cloud variables marked as sensitive or in HashiCorp Vault. Storing secrets in version control systems or plaintext files is not recommended.

Detailed Explanation:

Rationale for Correct Answer: terraform destroy destroys all resources managed by the current configuration, but it is not the only way to remove infrastructure. You can also remove a resource block from the configuration and run terraform apply; Terraform will then plan to destroy that specific resource because it is no longer declared.

Analysis of Incorrect Options (Distractors):

A. True. Incorrect. Terraform can destroy infrastructure through normal apply operations when resources are removed from configuration.

Key Concept: Terraform reconciles real infrastructure with configuration. Removing a resource from configuration and applying the change can destroy that resource.

The required_providers block is used to specify the provider versions that the configuration can work with. The version argument accepts a version constraint string, which must be enclosed in double quotes. The version constraint string can use operators such as  > =, ~ > , =, etc. to specify the minimum, maximum, or exact version of the provider. For example, version = " > = 3.1 "  means that theconfiguration can work with any provider version that is 3.1 or higher. References = [Provider Requirements] and [Version Constraints]
