HashiCorp Certified: Terraform Associate

Which statement accurately distinguishes a Terraform resource from a Terraform data source?

Why is Infrastructure as Code generally considered to reduce human error compared to manual infrastructure changes?

A team uses the same Terraform configuration, with only a few input differences, to create their development, staging, and production environments. Which IaC benefit does this best illustrate?

Which statement best describes why storing Terraform configuration files in a version control system (such as Git) is considered a core IaC practice?

What role does the Terraform Registry play in a typical Terraform workflow?

A configuration declares a provider block with credentials and a region, followed by several resource blocks that reference resource types from that provider. What is the relationship between the provider and the resources here?

A team maintains a Terraform configuration that provisions virtual machines, and separately uses a configuration management tool to continuously enforce package versions on those same machines after they boot. One engineer proposes replacing the configuration management tool entirely with more frequent terraform apply runs against slightly modified machine resource definitions. What is the most accurate assessment of this proposal, given Terraform's typical paradigm?

Two engineers each write a configuration to reach the same desired end state for a small environment: one lists an explicit ordered sequence of provider API calls to run, and the other writes an HCL configuration describing only the resources that should exist. Both configurations, when fully executed, produce an identical set of infrastructure objects. Which statement correctly classifies the two approaches?

A configuration includes both a resource block managing a database instance and a data source block referencing a security group that was created outside of Terraform by another team. Terraform is then run with a plan that only touches the database resource. What happens to the security group referenced by the data source during this run?

A JSON-syntax Terraform configuration file (.tf.json) and an HCL configuration file (.tf) both live in the same module directory, and each defines a different resource. Which statement about this setup is accurate?
