Terraform Associate 003: HashiCorp Certification Guide

Terraform Associate 003 is a 60-minute open-book exam that DevOps hiring managers actually respect. It costs USD 70.50, sits online-proctored, and - done right - takes three weekends to prepare for. This guide walks the eight objectives, the CLI commands you must memorize, and the field-tested plan I used to pass with 89%.

§What changed in 003 (from 002)

The 003 version, launched in early 2024, dropped Terraform 0.12 legacy content and added HCP Terraform (formerly Terraform Cloud) coverage. Expect 5–7 questions on workspaces, run tasks, and Sentinel policies - none of which appeared in 002.

§Exam format at a glance

• 60 minutes
• 57 questions (multiple choice, multi-select, true/false, fill-in-the-blank)
• Pass mark: 70%
• Open book: HashiCorp docs allowed - but you don't have time to search
• USD 70.50 via PSI proctored online
• Valid for 2 years

§Exam domain weighting

§Concepts that repeat on the exam

• terraform init downloads providers and configures backend - always safe to re-run
• terraform plan shows the diff - never modifies state
• terraform apply -auto-approve skips confirmation (know when this is dangerous)
• terraform state mv/rm surgery vs terraform import (real-world question)
• terraform workspace ≠ HCP workspace - the exam tests this trap
• Sensitive variables masked in output but still visible in state file
• Lifecycle: create_before_destroy, prevent_destroy, ignore_changes

§The study plan

• Days 1–4: Read the official HashiCorp study guide, install Terraform 1.6+, write your first main.tf against a free AWS/Azure account
• Days 5–9: CLI drills - init, plan, apply, destroy, fmt, validate, taint, workspace, state list/mv/rm - do each 10 times until muscle memory
• Days 10–14: Modules & state - build a 3-tier module, publish to registry, migrate local state to S3+DynamoDB backend
• Days 15–18: HCP Terraform trial - create workspace, connect GitHub, run Sentinel policy, VCS-driven plan/apply
• Days 19–21: 4 mock exams (Bryan Krausen on Udemy is closest to real). Target 90%+ before scheduling

§Answer patterns and exam-day tips

• Answers containing 'immutable infrastructure' or 'declarative' are usually correct in concept questions
• 'terraform state rm' does NOT destroy - it only removes from tracking
• Remote backends enable state locking; local backend does NOT
• Provider version constraints go in required_providers, not in resource blocks
• When in doubt on CLI, the answer is the least destructive command

§Salary reality - Bangladesh, UAE, KSA and remote

§Best resources

• HashiCorp official study guide (free)
• Bryan Krausen Udemy course + practice exams
• learn.hashicorp.com tutorials - free hands-on
• Terraform: Up & Running (Yevgeniy Brikman) - deeper than the exam
• HashiCorp docs - bookmark 'CLI Commands' and 'Configuration Language' tabs

§Final take

Terraform Associate 003 is one of the higher-signal credentials on the Certification Guides pillar at KNScert. Prepare on real systems, avoid dumps, and treat the exam as a byproduct of daily practice rather than a memorization sprint. If you follow the plan above and hit 80%+ on quality mock exams, you'll pass with margin.
