Can one remote backend configuration map to multiple workspaces?

A remote backend configuration can indeed be set up to support multiple workspaces. When using a remote backend, such as Terraform Cloud or AWS S3, the backend allows you to manage your Terraform state file in a central location. Each workspace corresponds to a different state file, which means that you can have multiple workspaces using the same backend configuration concurrently.

This flexibility facilitates the management of different environments or versions of your infrastructure, such as development, staging, and production, without needing separate backend configurations for each one. For example, you might use a single S3 bucket as a backend while having multiple workspaces for managing distinct environments.

The other options imply limitations that do not accurately reflect the capabilities of remote backend configurations with respect to workspaces. While the backend must be configured to support the desired workspaces, it is not restricted to just one or dependent on any specific conditions, allowing for both single and multiple workspace mappings.
