Exam Terraform Associate topic 1 question 57 discussion

Dear ALL, tested in Lab and Answer is : B

B!!!!!!!!

why is it index number AND name, though? i would have thought that specifying the index number is enough

To reference the "name" value of the second instance of the fictitious resource "aws_instance" named "server", you can use the element index notation in Terraform. The element index notation allows you to access elements in a list or collection by their index. Given that the index in Terraform starts from 0, the second instance has an index of 1. Therefore, to reference the "name" value of the second instance = B

A. element(aws_instance.web, 2) is correct if we want to access the 3rd one, but there is no "the third one"

because the index starts from 0 so second instance name will be at 1

B for sure

This is the very basics of terraform resource referencing

Example: resource "aws_instance" "web" { count = 2 name = "terraform-${count.index}" } output "second_instance_name" { value = aws_instance.web[1].name }

The answer is B, aws_instance.web[1].name

B is correct

B is a correct answer, checked.

The count.index starts from 0. Therefore, the second instance would have an index of 1. In that case, the correct answer would be B. aws_instance.web[1].name.

its B - people who answer incorrectly with such conviction and belief are dangerous.

Tried and tested, definitely B

The output of A won't return the name of the 2nd instance. So here the answer is "B"

B is the correct answer
