Exam Terraform Associate topic 1 question 283 discussion

Answer C The question asks how to output the value in the cli, if we declare output only in a child module it will not be shown in the cli, we need one more output in the root configuration

this question is a replica of question 232. Answer given was B. Declare the output in the child module.

n a parent module, outputs of child modules are available in expressions as module.<MODULE NAME>.<OUTPUT NAME>. For example, if a child module named web_server declared an output named instance_ip_addr, you could access that value as module.web_server.instance_ip_addr

Looked this up on another testing engine ( O'Reilly ) and it has "C" as the correct answer.

question is weird.. If both in C become any it would be C

C is correct. child>parent and parent>CLI

C is correct. To print to the CLI it will also need to be declared in the root config

There is no need to set the output in the root module.

You can use outputs.tf in the child module and the output block in the root module.

B. Declare the output in the child module. To output returned values from a child module in the Terraform CLI output, you need to declare the output in the child module. Option A, declaring the output in the root configuration, is incorrect because the output is defined in the child module. Option C, declaring the output in both the root and child module, is also incorrect because this would create duplicate outputs. Option D, none of the above, is incorrect because there is a way to output returned values from a child module in the Terraform CLI output.

1. To pass a value from child module to parent module, it must declare the output variable in child module. 2. To print out a value, it must declare the output variable in parent module.

to output returned values from a child module to CLI - Declare the output in both the root and child module. For example: child-module.tf output "child_foo" { value = "foobar" } main.tf module "child" { source = "path/to/child" } output "output_to_cli" { value = module.child.child_foo }

B is correct answer

In a parent module, outputs of child modules are available in expressions as module.<MODULE NAME>.<OUTPUT NAME>. For example, if a child module named web_server declared an output named instance_ip_addr, you could access that value as module.web_server.instance_ip_addr.
