A team uses Terraform to manage network devices. They recently changed the provider version and now `terraform plan` shows that all resources need to be replaced. What is the most likely cause?

The provider version change altered the resource schema, causing Terraform to see differences

The configuration files were reformatted with `terraform fmt`

Which of the following is a recommended practice for managing Terraform state in a team environment?

Store state in a version control repository without any backend

Keep state files locally on each developer's machine

Delete the state file after every apply to avoid clutter

Store state remotely in a shared backend such as an S3 bucket or Azure Storage

What is the purpose of a Terraform provider?

To store the current state of the infrastructure in a backend

To execute provisioning scripts on virtual machines

To define the syntax rules for HCL configuration files

To translate Terraform configuration into API calls for a specific platform

A Terraform configuration uses the Junos provider. The engineer wants to pass the device's SSH credentials to the provider without hardcoding them in the configuration file. What is the recommended approach?

Use a `variable` block with a default value

Put the credentials in the provider block

Store the credentials in a `terraform.tfvars` file
