Key Areas Covered in the Terraform-Associate-003 Exam

1. Infrastructure as Code (IaC)
   One of the foundational concepts tested in this exam is Infrastructure as Code (IaC). Terraform allows you to manage your infrastructure using declarative configurations. You'll be tested on your ability to write, validate, and apply configuration files to automate infrastructure deployment.

2. Terraform Core and Workflow
   The Terraform workflow involves initializing your working directory, planning and previewing the changes to your infrastructure, and applying those changes. Understanding this workflow and the Terraform core, which provides the execution of plans and management of state, is essential for success in the exam.

3. Terraform State
   The concept of Terraform State is critical to maintaining a record of your managed infrastructure and mapping real-world resources to your configuration. You must understand how Terraform uses state to enable correct configuration and its role in performance and scalability.

4. Providers and Modules
   Terraform uses providers to interface with cloud platforms, on-prem solutions, and other services. Understanding how to configure and use providers effectively is essential for managing your infrastructure. You’ll also need to demonstrate your ability to build reusable and scalable modules to organize and share configurations.

5. Security Best Practices
   Security is a significant part of the exam. Understanding how to apply security best practices in your Terraform configurations, such as securing sensitive data, managing access controls, and configuring least privilege for your infrastructure, is key.
