You would like to reuse the same Terraform configuration for development and production with different state files; which command would you use?

• A. terraform state
• B. terraform init
• C. terraform import
• D. terraform workspace

Answer: (D)

Workspaces let you have separate state files for each environment while reusing the same configuration. By creating and switching between workspaces, Terraform uses a distinct state for development and production, so you can apply changes in one environment without affecting the other. You’d create or select a development workspace, then run plan and apply, and repeat with a production workspace for its state. The other commands don’t provide this per-environment state separation: the state subcommand only manipulates the state file, init prepares the working directory and downloads providers, and import brings existing resources into state.
