Terraform Associate Skills Measured

IaC questions test why declarative configuration matters. Terraform stores desired infrastructure in versioned files, then computes changes against state and provider APIs. The common trap is treating Terraform like a procedural script. Terraform does not run every line in order; it builds a dependency graph and acts on resources based on references and lifecycle rules.

Providers, provider versions, authentication, and state are foundational. Provider blocks configure plugins, resources manage remote objects, and state binds resource addresses to real objects. If a question mentions multi-cloud or service-agnostic workflows, look for the provider model rather than a single cloud-specific console workflow.

`init`, `validate`, `fmt`, `plan`, `apply`, and `destroy` each answer a different operational question. `init` prepares the directory, `validate` checks configuration structure, `fmt` normalizes style, `plan` previews changes, `apply` executes, and `destroy` removes managed objects. The exam often asks which command gives information without changing infrastructure.

Configuration questions usually test resources versus data sources, attribute references, variables, outputs, complex types, expressions, functions, dependencies, and validation. If a value should be reusable or environment-specific, use variables. If another stack or operator needs a result, expose an output. If Terraform cannot infer dependency order from references, consider `depends_on` carefully.

Modules package reusable configuration, but they introduce scope and versioning decisions. Variables are inputs to a module, outputs expose selected values, and sources identify where the module code comes from. A mistake in module review is assuming child modules can see parent variables automatically; inputs must be passed explicitly.

State management questions ask what Terraform knows, not just what exists in the cloud. Remote state, backend configuration, state locking, imports, drift, and `terraform state` inspection all matter. If existing infrastructure must become Terraform-managed, importing maps the object into state but does not magically write perfect configuration for every argument.

HCP Terraform questions focus on remote runs, shared state, workspaces, projects, VCS integration, collaboration, and governance. It is not simply “Terraform in a browser.” The exam distinction is whether the problem calls for local CLI work or a team workflow with managed runs, policy checks, shared variables, and workspace organization.
