Which of the following has the highest precedence when assigning a value to an input variable?

Environment variables (TF_VAR_*)

How can a root module access an output value from a child module?

By reading the state file directly

By declaring a variable in the root module

A root module has an output `vnet_id` from a child module. The root module also defines its own output `vnet_id`. Which statement is true?

The child module output is accessible as `var.vnet_id`.

The root output and child module output cannot have the same name.

The root output will automatically inherit the child module output.

The root output can reference the child module output using `module.child.vnet_id`.

A variable `instance_type` is defined with type `string`. The team wants to ensure that only `t3.micro`, `t3.small`, or `t3.medium` are allowed. Which validation block correctly implements this?

validation { condition = contains(["t3.micro", "t3.small", "t3.medium"], var.instance_type) error_message = "Invalid instance type." }

validation { condition = var.instance_type != "" error_message = "Instance type cannot be empty." }

validation { condition = var.instance_type == "t3.micro" error_message = "Only t3.micro allowed." }

validation { condition = can(regex("^t3\\.", var.instance_type)) error_message = "Must start with t3." }
