In a Terraform configuration, where do you specify the state backend?

• A. The resource block
• B. The terraform block
• C. The provider block
• D. The datasource block

Answer: (B)

State backends determine where Terraform stores its state and how it manages locking and access. You configure this in the terraform block, using a backend configuration inside that block. For example, you can specify a remote or local backend there, such as an S3 backend with bucket, key, and region settings. After changing the backend, you run terraform init to initialize the new backend.

Resource blocks define the infrastructure you want to create, provider blocks configure authentication and API details for those services, and data source blocks read information from providers. Those are separate from where the state storage is defined, which is why the terraform block is the correct place to specify the state backend.
