Reflecting on HashiCorp Certified: Terraform Associate 002
In terms of my Terraform experience prior to the exams, I have yet to build any Terraform project at a production level. My recent exposure was mainly around trying to play around with CircleCI’s Nomad client Terraform setup.
In my past career, I have used loads of AWS CloudFormation. Yes, I have had some battle scars re: IaC. I always wanted to learn more about Terraform, given that it supports more than 1 cloud platform.
In particular, I am interested in contributing a Terraform provider for CircleCI. This means creating a provider/plugin for creating CircleCI webhooks / scheduled pipelines via Terraform for example.
This above may likely be a lofty ambition, but I thought I’d hedge this by also trying for the certification. Kill two birds in one quarter, as they say.
Breakdown of Score
|Content Area||Score (%)|
|Understand infrastructure as code (IaC) concepts||100|
|Understand Terraform’s purpose (vs other IaC)||100|
|Understand Terraform basics||85|
|Use the Terraform CLI (outside of core workflow)||100|
|Interact with Terraform modules||50|
|Navigate Terraform Workflow||100|
|Implement and maintain state||75|
|Read, generate and modify configuration||72|
|Understand Terraform Cloud and Enterprise capabilities||100|
Overall, I scored 84% (70% required).
Word of Advice
If you are not using Terraform on a daily basis, practice Terraform CLI commands definitely!
The exam has a few questions where they may test you to type the code / command required. See sample questions here.
I did have a “doh!” moment, since it wasn’t clear how “complete“ the answer should be.
In particular, one question I got was: How would you reference the
vpc_id from this module in the code snippet?
To reference the module output, it would be
module.aws_vpc.vpc_id for example. I think the full answer should be:
vpc_id = module.aws_vpc.vpc_id.
I had only typed
module.aws_vpc.vpc_id due to lack of clarity in the question. I think I likely lost points there!
In terms of studying for it, I highly recommend the following Udemy course + practice exam!
Lastly, there will be a newer exam version (003).
I understand this update would remove older questions referring to already-deprecated commands (e.g.,
So if you can wait, do go for the 003 version instead!
It was a fun exam to take, for sure!
Given that it is really about a tool and its ecosystem, I’d highly encourage folks to try out Terraform while practicing for the exam.
Your mileage on the Terraform tool will go a long way if you practice. This way, the exam questions will make way more sense too, as you practice.
