HashiCorp Certified: Terraform Associate (003) Exam Guide
The **Terraform Associate** certification validates your Infrastructure as Code (IaC) skills. It covers fundamental Terraform concepts, state management, modules, and Terraform Cloud/Enterprise features.
What is Infrastructure as Code (IaC)?
Answer : Managing and provisioning infrastructure through code (configuration files) rather than manual processes.
IaC enables repeatability, versioning, and automation of environment creation (servers, networks, etc.).
What is the purpose of the 'terraform.tfstate' file?
Answer : It stores the real-world state of the infrastructure managed by Terraform to map it to your configuration files.
It is Terraform's 'memory'. It should never be manually edited as it contains critical information about your resources.
Which Terraform command is used to view changes before applying them?
Answer : `terraform plan`.
This step is crucial to avoid costly mistakes by verifying exactly what Terraform will create, modify, or destroy.
What does the `terraform init` command do?
Answer : It initializes the working directory, downloads providers (AWS, Azure, etc.), and configures the backend.
This is the first command to run in a new project or after cloning an existing repository.
What is a Terraform 'Module'?
Answer : A container for multiple resources that are used together, allowing for code reuse.
Modules help organize code and create standardized infrastructure components.
