Which Terraform command migrates a workspace to a remote backend after updating your configuration?

• A. terraform apply
• B. terraform init
• C. terraform plan
• D. terraform refresh

Answer: (B)

Terraform backends specify where state is stored. When you update your configuration to use a remote backend, Terraform must reconfigure itself to use that backend and, if you have existing state, migrate it to the new one. The initialization step does exactly this: it reinitializes the working directory, pulls required providers, and configures or migrates the backend as specified. The other commands don’t change backend settings or move state; they plan, apply, or refresh using whatever backend is currently configured. So, running the initialization command is the action that migrates the workspace to the remote backend.
