What is the purpose of designing a module's interface with input variables and outputs?

To eliminate the need for provider configuration

To increase the number of resources in the module

To make the module compatible with all cloud providers

To abstract the underlying resources and expose only necessary information

A team has refactored a configuration into modules and added `moved` blocks. They run `terraform plan` and see no changes. However, they are concerned that the `moved` blocks might be masking a configuration error. What is the best way to verify the refactor is correct?

Compare the `terraform show` output before and after the refactor.

Run `terraform apply` and then `terraform plan` to confirm no changes.

Remove the `moved` blocks and run `terraform plan` to see if any changes appear.

Run `terraform validate` and `terraform fmt` to check for errors.

What is the primary purpose of extracting a set of resource blocks into a module?

To enable reuse of the configuration across multiple environments

To avoid the need for provider configuration

To make the configuration run faster

To reduce the number of state files in the workspace

A team is extracting a set of IAM policies into a module. The policies reference a common `account_id` variable. After moving the resources, they run `terraform plan` and see that the policies will be updated in place, not replaced. What is the most likely reason for this?

The module's variables are set to the same values as before, so Terraform sees no changes.

The resource addresses changed, but the `moved` block was added, so Terraform updates the existing resource in place.

The `moved` block was not added, so Terraform is updating the existing resource.

The policies are not actually managed by Terraform, so it updates them in place.

After moving resources into a module, what must be updated in the root module to reflect the new modular structure?

Change the backend configuration

Remove the provider configuration

Add a module block that calls the new module
