A developer reports that `terraform apply` fails with an authentication error from the AWS provider. The developer is using the same credentials that work in the AWS CLI. What is the most likely cause?

The Terraform state file is corrupted.

The provider is configured with a different set of credentials than the CLI.

The provider version is too old.

The AWS region is not set in the provider block.

A provider fails with an error that does not include the resource ID. You need to identify which resource is causing the failure. What is the most efficient way to find this?

Enable TF_LOG=TRACE and search the logs for the resource type and operation.

Run `terraform state list` to see all resources.

Run `terraform plan` with `-refresh=false` to isolate the issue.

Check the provider documentation for common errors.

While analyzing TF_LOG=TRACE output for a failing Azure provider operation, you notice a line containing: "[DEBUG] azurerm: AzureRM Request: https://management.azure.com/subscriptions/.../resourceGroups/rg-prod?api-version=2021-04-01 Status Code: 404". What does this log entry indicate?

The resource group was not found

A team uses the Google Cloud provider. `terraform plan` fails with `Error: google: could not find default credentials.` The developer has `GOOGLE_APPLICATION_CREDENTIALS` set to a service account key file. What is the most likely issue?

The provider version is too old to support service account keys.

The Terraform state file is locked.

The provider is configured with the wrong project ID.

The service account key file is invalid or expired.
