Hands-on Practice
- Set up a cloud free tier account (AWS, Azure, or GCP) and practice daily
- Build at least 10-15 different Terraform configurations from scratch
- Practice destroying and recreating infrastructure to understand the full lifecycle
- Intentionally break configurations to learn troubleshooting
- Use terraform plan extensively to understand what changes will occur
CLI Command Mastery
- Run every terraform command at least 20 times - muscle memory matters
- Practice using flags and options for common commands (apply -auto-approve, plan -out, etc.)
- Learn to read terraform plan output quickly and accurately
- Memorize the purpose of each terraform state subcommand
- Create flashcards for command syntax and common flags
HCL Syntax Fluency
- Write configurations by hand, not just copy-paste from examples
- Practice variable interpolation syntax (${var.name} vs var.name)
- Learn to recognize syntax errors quickly
- Understand the difference between resource, data, and module blocks at a glance
- Study meta-arguments (count, for_each, depends_on, lifecycle) in depth
State File Understanding
- Examine state files directly (terraform show) to understand their structure
- Practice configuring remote backends (S3, Azure Storage, etc.)
- Learn to use terraform state commands without fear
- Understand state locking and when it occurs
- Know how to recover from state file corruption or loss scenarios
Module Expertise
- Use at least 5-10 different modules from the Terraform Registry
- Create your own module and use it in multiple configurations
- Understand module versioning constraints (~>, >=, etc.)
- Practice passing complex data types to modules
- Study well-designed public modules to learn best practices
Exam-Specific Preparation
- The exam is scenario-based - practice reading code snippets quickly
- Know the difference between Terraform OSS, Cloud, and Enterprise features
- Understand which features require Terraform Cloud/Enterprise
- Review the official sample questions multiple times
- Take practice exams under timed conditions (60 minutes)
- Focus on WHY answers are correct, not just memorizing them
Common Pitfalls to Avoid
- Don't confuse provider version constraints with Terraform version constraints
- Remember that terraform destroy doesn't delete the state file
- Understand that not all changes can be detected by terraform plan
- Know when implicit dependencies work vs when explicit depends_on is needed
- Remember that local-exec and remote-exec provisioners are last resort options
Exam Day Tips
- 1The exam is 57 questions in 60 minutes - that's about 63 seconds per question, so pace yourself
- 2Read questions carefully - some ask for 'best' answer, others ask for 'all that apply'
- 3Flag difficult questions and return to them - don't get stuck on any single question
- 4Watch for questions about Terraform Cloud/Enterprise features vs OSS features
- 5Many questions include code snippets - read them carefully for syntax errors or logic issues
- 6Eliminate obviously wrong answers first to improve your odds on uncertain questions
- 7Remember that you need 70% to pass - missing 17 questions is acceptable
- 8The exam is scenario-based, not pure memorization - think about real-world usage
- 9Remote proctored exam requires quiet space with stable internet and working webcam
- 10Arrive 15 minutes early to complete check-in process and system checks
- 11No external resources allowed - no documentation, notes, or second monitors
- 12Have government-issued photo ID ready for identity verification
- 13Take a deep breath - if you've done hands-on practice, you're ready
