Terraform Certification
Terraform Associate
(004)
How I passed the Hashicorp Terraform Associate (004) certification on my first attempt. Below I will outline why I took the certification, my approach and the knowledge gained.
Why I Pursued This Certification
Following my AZ-104 studies, I realised how tedious and time-consuming it can be to navigate and provision resources using the Azure Portal. This led me to discover Terraform, a tool used to define and provision large-scale cloud resources using code.
Using code has several benefits including greater consistency by reducing human error, version control to allow changes to be tracked and scalability by integrating with CI/CD pipelines to automate infrastructure deployments. This certification introduced concepts such as state management, providers and dependency locks.
Key Topics Covered
Infrastructure as Code (IaC)
Managing infrastructure using configuration files rather than manual deployments.
Terraform Workflow
Understanding the plan, apply and destroy lifecycle used to manage resources.
State Management
Tracking infrastructure through state files and understanding remote state concepts.
Providers & Resources
Using providers to interact with cloud platforms and define infrastructure components.
Modules
Building reusable and scalable infrastructure configurations.
Variables & Outputs
Creating reusable configurations and passing information between resources.
How I Studied & Passed
Official HashiCorp Website
The HashiCorp website was my primary learning resource. I completed the learning path and took handwritten notes as I progressed. I worked through all aspects of the exam and reviewed the exam content list.
Practice with Terraform
I spent a large amount of time creating resources, breaking configurations and fixing mistakes in my code. Repeating all the processes helped to consolidate the concepts in the exam.
SkillCertPro Practice Exams
The SkillCertPro practice exams helped me identify weaker areas and become familiar with the style of questions asked in the certification. Once I was consistently scoring above 85%, I felt confident booking the exam.
In short: I found the best approach was practice with Terraform alongside SkillCertPro exams. As I sat the certification shortly after the update, there were fewer practice resources available compared to the 003 exam. This was the most difficult certification I have passed.
Mock Exams Visualised
The Power BI line graph depicts my practice exam results. By recording results over time, I was able to monitor my progress and determine when I was consistently scoring well above the pass mark before booking the exam.

What I struggled with
Terraform syntax was probably the biggest challenge for me. It took a significant amount of time to understand what each block of code was doing and how everything connected together. Since I do not directly use Terraform during my work, it required a large time commitment at home.
I also found there to be fewer practice exams available after the certification update. As a result, I spent more time learning through documentation and by building several projects to provision cloud resources.
Closing Remarks
Terraform gave me a much better understanding of how cloud infrastructure is managed in larger environments. It was interesting to see how tasks that would normally take multiple clicks in the Azure Portal could be defined and deployed using code.
Overall, I found the certification both practical and enjoyable. By far the hardest certification I studied and passed. It introduced concepts that I expect to encounter throughout my career and gave me a solid foundation in Infrastructure as Code.
