Detailed highlights and study suggestions
- Infrastructure as Code Fundamentals
- Learn core IaC concepts: reproducibility, version control of configs, and automated provisioning.
- Understand why Terraform is suited for multi‑cloud automation and how it differs from configuration management tools.
- Terraform Fundamentals
- Know what a provider is and how provider plugins enable Terraform to interact with platforms and APIs.
- Recognize how Terraform represents infrastructure in state and why state consistency matters.
- The Core Terraform Workflow
- Practice the daily lifecycle:
terraform init— initialize working directory and download providers/modules.terraform plan— preview changes.terraform apply— execute changes.terraform destroy— remove resources.
- Know when to run
terraform fmtandterraform validateas part of CI checks.
- Configuration
- The largest exam objective. Be fluent writing:
resourceblocks,datasources,variableandoutputdeclarations.- Built‑in functions (e.g.,
lookup,format,join) and expressions. - Explicit dependencies via
depends_onand implicit dependencies through interpolation. lifecyclemeta-arguments (create_before_destroy,prevent_destroy).
- Manage sensitive values carefully so secrets aren’t exposed in state or logs.
- Modules
- Author modules with clear inputs/outputs and sensible defaults.
- Consume modules from the Registry, Git, or local paths.
- Apply semver for module versioning and pin versions in your configurations.
- State Management
- Compare local vs. remote backends and why remote backends with locking (e.g., S3 + DynamoDB, Terraform Cloud) are recommended for teams.
- Practice recovering from state drift and partial failures.
- Apply best practices for encrypting and limiting access to state.
- Maintenance (Day-Two Operations)
- Use
terraform importto bring existing resources under management. - Use
terraform statesubcommands to inspect and modify state safely. - Enable verbose logging with
TF_LOGfor troubleshooting:TF_LOG=DEBUG terraform apply.
- HashiCorp Cloud Platform (HCP) / Terraform Cloud Features
- Get hands‑on with workspaces, remote runs, VCS integration, and state storage hosted on Terraform Cloud/HCP.
- Study collaboration features and governance (policy as code). The 004 exam expanded this area—practical experience is important.
This course is organized around these eight objectives. Each lesson pairs a focused lecture with practical labs so you can learn concepts and build real‑world Terraform workflows you’ll be tested on.
- If you prepared for exam version 003, be aware that version 004 expanded coverage—especially for Terraform Cloud / HCP and collaboration/governance features. Review the official exam guide and get hands‑on with Terraform Cloud functionality before scheduling the exam.
