HashiCorp Certified: Terraform Associate (003) Practice Exam: 100 Questions

HashiCorp Certified: Terraform Associate (003) Practice Exam

Validate your Infrastructure as Code (IaC) mastery and prepare for the HashiCorp Certified: Terraform Associate (003) certification exam with this 100-question practice test. Built for DevOps engineers, cloud architects, and site reliability specialists, this test covers the core workflow, syntax, and operational mechanics of Terraform Open Source and Terraform Cloud.

Official Terraform Associate (003) Curriculum

The questions assess all nine core objectives defined by HashiCorp:

• Understand Infrastructure as Code (IaC) Concepts: Declarative vs imperative configuration models, idempotent infrastructure updates, drift detection, and modular version-controlled deployments.
• Understand the Purpose of Terraform (vs Other Software): Comparison with configuration management systems (Ansible, Chef, Puppet) and provider-specific provisioning tools (CloudFormation, ARM/Bicep).
• Understand Terraform Basics: Provider configuration, multiple provider aliases, resource declarations, data source queries, local values (locals), input variables (types, defaults, validation rules), and output values.
• Use the Terraform CLI (Outside of Core Workflow): terraform fmt style standardization, terraform validate configuration verification, terraform taint and terraform untaint (and -replace flag in apply), terraform import resource mapping, terraform state subcommands (list, show, mv, rm), and terraform output.
• Interact with Terraform Modules: Sourcing modules from local directories, Git repositories, and the public/private Terraform Registry; input/output variable binding; and module version pinning.
• Navigate the Core Terraform Workflow: Executing terraform init (downloading providers, initializing backends), terraform plan (interpreting execution plans, generating speculative plan files), and terraform apply / terraform destroy.
• Implement and Maintain State: Purpose of the state file (terraform.tfstate), state locking mechanisms (DynamoDB, Consul), remote backends (Amazon S3, Azure Blob, Google Cloud Storage, Terraform Cloud), remote state data sources, and handling sensitive data in state files.
• Read, Generate, and Modify Configuration: HashiCorp Configuration Language (HCL) syntax, expressions, built-in functions (lookup, element, merge, can, length), dynamic blocks, count vs for_each meta-arguments, lifecycle rules (create_before_destroy, prevent_destroy, ignore_changes), and resource dependencies (depends_on).
• Understand Terraform Cloud Capabilities: Workspaces, VCS-driven workflows, remote execution, Sentinel policy-as-code, and private module registries.
