Question

A team maintains a reusable VPC module in ./modules/network. The module declares a variable named subnet_cidrs of type list(string) with no default. In the root module, an engineer writes a module block referencing this module but the plan fails with an error stating the required variable was not provided. Which change to the root module block correctly supplies the value?

Accepted Answer

Add an argument inside the module block: subnet_cidrs = ["10.0.1.0/24", "10.0.2.0/24"]

Answer

Add a variable "subnet_cidrs" {} block inside the module block to declare the input

Answer

Reference the value using module.network.subnet_cidrs in the module block

Answer

Add an output "subnet_cidrs" block to the child module so the value propagates automatically
