HashiCorp Terraform Associate (004) Certification Guide

Step 1: Learn the exam facts

The current exam is Terraform Associate (004), which tests Terraform 1.12. It is a one-hour, multiple choice exam, delivered online with proctoring in English. HashiCorp's page listed the price at 70.50 USD plus local taxes, with no free retake. The credential lasts two years. Question count and passing score were not stated on the page.

Step 2: Study the eight objectives

HashiCorp lists eight objective areas without percentage weights, so prepare for all of them. The core workflow, configuration, and state sections are where most hands-on experience pays off.

1. Infrastructure as Code (IaC) with Terraform
2. Terraform fundamentals
3. Core Terraform workflow
4. Terraform configuration
5. Terraform modules
6. Terraform state management
7. Maintain infrastructure with Terraform
8. HCP Terraform

Step 3: Master the core workflow

Be completely comfortable with init, validate, plan, apply, and destroy, and know what each one does and when. Understand how providers are installed and versioned, and how the dependency lock file works. Know fmt, and how plan files and apply differ.

terraform init
terraform fmt -check
terraform validate
terraform plan -out=tfplan
terraform apply tfplan
terraform destroy

Step 4: Practice configuration and modules

Write configurations that use variables, outputs, locals, data sources, count and for_each, dynamic blocks, and functions. Understand variable precedence and sensitive values. Create a small reusable module and call it from a root module, and know how to source modules from the registry and pin versions.

variable "env" {
  type    = string
  default = "dev"
}

resource "local_file" "example" {
  filename = "hello.txt"
  content  = "environment: ${var.env}"
}

Step 5: Understand state and HCP Terraform

State maps your configuration to real resources, so learn local versus remote backends, state locking, terraform state subcommands, import, and why state files can contain secrets and must be protected. For HCP Terraform, know workspaces, remote runs, variable sets, policy checks, and team access at a conceptual level. Practice with a free account if possible.

Step 6: Prepare and recertify

Use HashiCorp's study guide and sample questions, and build real infrastructure in a throwaway free-tier cloud account or with the local and docker providers. Take timed practice questions to build speed on a one-hour exam. To recertify, pass the current Associate exam starting six months before expiry, or pass a higher-level HashiCorp exam to extend it.
