Which Terraform command initializes the configuration directory, setting up the backend and modules for subsequent operations?

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

Answer: (B)

Initializing the configuration directory is about preparing Terraform to run by gathering the necessary pieces it needs to work—provider plugins, modules, and the backend where state is stored. The command that does this is terraform init. It sets up the backend (local or remote), fetches module sources defined in the configuration, and installs the required provider plugins so Terraform can communicate with the target infrastructure. Without this initialization, Terraform wouldn’t have the modules or providers loaded, and the state handling wouldn’t be configured, so subsequent steps like planning or applying wouldn’t run correctly. Other commands handle planning, applying changes, or refreshing state, but they assume the workspace has already been initialized and the necessary plugins and modules are in place.
