Which of the following is available only in Terraform Enterprise or Cloud workspaces and not in Terraform CLI?

• A. Secure variable storage
• B. Support for multiple cloud providers
• C. Dry runs with terraform plan
• D. Using the workspace as a data source

Answer: (A)

This is about secrets handling in Terraform. Terraform Cloud and Enterprise workspaces provide a secure variable storage feature that keeps sensitive values encrypted and masked, tied to the workspace. In the Terraform CLI, there isn’t a built-in secure storage area for variables within a workspace; secrets must be supplied through environment variables, tfvars files, or external secret management solutions, which is less centralized and automatic.

The other options aren’t exclusive to the Cloud/Enterprise workflow. You can work with multiple providers and run plans in both CLI and Cloud, and using a workspace as a data source is a capability that exists with the Terraform Cloud/Enterprise ecosystem via its data sources, not a unique feature of the CLI in the same sense.
