Which command would you run to automatically format Terraform configuration files to meet standard style guidelines?

• A. terraform fmt
• B. terraform fmt -check
• C. terraform validate
• D. terraform apply

Answer: (A)

Formatting Terraform configuration to a consistent style is done with the built-in formatter. Running terraform fmt reads your .tf files and rewrites them to follow the standard Terraform style, producing consistent indentation, spacing, and layout across resources, blocks, and arguments. By default it edits files in place, so your code is updated automatically to the canonical form. The other options serve different purposes: -check only reports what would be reformatted without changing files, validate checks syntax and references, and apply actually provisions changes to infrastructure. So the command that automatically formats files is terraform fmt.
