HashiCorp Terraform Associate (003) prep, adaptive plan with ARIA
The HashiCorp Terraform Associate is the entry-level IaC cert most relevant for engineers writing Terraform on cloud teams in 2026. 60 minutes, 57 questions, multiple choice and multiple response only. Online proctored, no labs.
What the exam is
Nine objectives in the 003 version:
| Objective | Focus |
|---|---|
| 1. IaC concepts | Why IaC, immutable vs mutable, declarative vs imperative |
| 2. Terraform purpose | Where it sits relative to providers, what it manages |
| 3. Terraform basics | Init, plan, apply, destroy, state, drift |
| 4. Outside core workflow | Import, state operations, taint and replace |
| 5. Modules | Local, registry, versioning, source paths |
| 6. Workflow | Init, validate, plan, apply, destroy, fmt |
| 7. State | Local, remote, locking, sensitive data |
| 8. Configuration | Variables, locals, expressions, dynamic blocks, functions |
| 9. Cloud and HCP | Workspaces, run triggers, version control integration |
Passing score 70 percent. The cert is valid for two years.
How ARIA preps you for it
The CAT eval lands a per-objective skill estimate after fifteen to twenty-five questions. Most candidates land heavy on State and Modules, because lock conflicts, drift detection, and module source-syntax questions catch engineers who used Terraform without ever fixing a broken state file. The roadmap weights phases to your gaps.
The error backlog tags every miss by command family (init, plan, apply, state, import, taint) and by concept (state locking, sensitive variables, expression order). Wrong answers around state operations resurface fast, because that is also where production teams break things.
Common pitfalls on this cert
Confusing terraform plan with terraform apply behavior. Plans show intent, applies execute. Several questions hinge on which side a refresh runs on.
Skipping HCL function syntax. The exam tests built-in functions. Memorize the syntax of the dozen most common: lookup, length, element, merge, concat, format, jsondecode, file, fileexists, contains, can, try.
Treating modules as folders. Modules have a source attribute, a version constraint, and rules about input and output blocks. Use the registry mental model.
