In Terraform, what is the name of the output used to expose the VPC ID in the example?

• A. outvpc_id
• B. vpc_id
• C. module_vpc_id
• D. vpc_out_id

Answer: (A)

Outputs in Terraform are blocks that declare a value to be exposed outside of a module or to be shown to the user. The name you give an output is how you reference that value elsewhere, so choosing a clear, descriptive name matters. In the example, the VPC's ID is exposed through an output named outvpc_id, which is exactly what you would use to refer to the VPC ID from other modules or from the root module’s outputs. If you’re within a module named vpc, you would access it as module.vpc.outvpc_id. The other candidate names do not match the defined output in the example, so they wouldn’t be the correct reference.
