The statement is false because a single remote backend configuration block in Terraform does not always map to a single remote workspace. While it is possible to create a one-to-one mapping using the workspaces.name attribute, the remote backend also supports the workspaces.prefix attribute. When prefix is used, the single backend configuration can map to multiple remote workspaces that share the specified prefix. The user can then switch between these workspaces using the terraform workspace select command.

The statement "True" is incorrect because it makes an absolute claim ("always") that is invalidated by the existence and functionality of the workspaces.prefix attribute in the remote backend configuration. This feature explicitly allows a single configuration to be associated with a group of workspaces, not just one.

1. HashiCorp Terraform Documentation

"Backend Configuration - remote": In the "Configuration Variables" section for the remote backend

the documentation describes the workspaces block. It states: "A workspaces block can be specified to override the default workspace selection behavior. A workspaces block can contain either a name or a prefix attribute." It further clarifies that prefix allows the configuration to be used with any workspace name that has the given prefix. This directly contradicts the idea of a permanent one-to-one mapping.

2. HashiCorp Terraform Documentation

"Workspaces": In the section on "Remote Workspaces"

the documentation explains how a configuration's backend block connects it to a workspace in Terraform Cloud. It notes

"When using a remote backend

the Terraform CLI maps each workspace to a corresponding workspace in the remote system." The mechanism for this mapping

as detailed in the backend configuration

includes the flexible prefix option

allowing one configuration to map to many potential workspaces.
