HashiCorp Updated Terraform-Associate-003 Exam Questions and Answers by peyton

When the state file is locked, operations that modify or depend on the state (liketerraform apply,terraform destroy, andterraform state list) are blocked.terraform fmtonly formats the configuration files and does not interact with the state, so it is allowed.

Terraform providers are not always installed from the Internet. There are other ways to install provider plugins, such as from a local mirror or cache, from a local filesystem directory, or from a network filesystem. These methods can be useful for offline or air-gapped environments, or for customizing the installation process. You can configure the provider installation methods using the provider_installation block in the CLI configuration file.

Some backends support state locking, which prevents other users from modifying the state file while a Terraform operation is in progress. This prevents conflicts and data loss. Not all backends support this feature, and you can check the documentation for each backend type to see if it does.

Sentinel policies are checked after the plan stage of a Terraform run, but before it can be confirmed or the terraform apply is executed3. This allows you to enforce rules on your infrastructure before it is created or modified.
