A Terraform configuration uses a provider that requires authentication. The engineer wants to ensure that credentials are not exposed in the configuration or state file. What is the most secure approach?

Use a `variable` block with a default value

Use environment variables for credentials and ensure the provider does not store them in state

Store credentials in a `terraform.tfvars` file and commit it

Hardcode the credentials in the provider block

A team has been using Terraform to manage a test environment. They now want to remove all resources that were created by Terraform. What command should they run?

`terraform state rm` for each resource

A network team wants to version control their infrastructure configuration. They plan to use Terraform and want to ensure that changes are reviewed before being applied. What is the best practice?

Run `terraform apply` directly on the production environment

Store Terraform configuration in a Git repository and use pull requests for changes

Keep the configuration only on the lead engineer's laptop

Use `terraform fmt` to format the code and then apply

What is the primary purpose of Terraform state?

To log all actions performed by Terraform for auditing purposes

To track the current configuration of managed infrastructure resources

To cache the Terraform binary for faster execution

To store the credentials used to authenticate to cloud providers

A Terraform configuration includes a resource that depends on another resource. The engineer wants to ensure that the dependency is explicit and not inferred. What should the engineer do?

Add a `depends_on` argument to the dependent resource

Use `terraform apply -parallelism=1`

Use `terraform graph` to visualize dependencies

Run `terraform plan` to see the order
