HashiCorp Certified: Terraform Associate — Question 8

Which of the following is the correct way to pass the value in the variable num_servers into a module with the input servers?

Answer options

• A. servers = num_servers
• B. servers = variable.num_servers
• C. servers = var(num_servers)
• D. servers = var.num_servers

Correct answer: D

Explanation

The correct answer is D because it correctly references the num_servers variable as an attribute of the var object. Option A incorrectly tries to directly assign the variable without referencing its container, while B uses 'variable' instead of 'var', and C incorrectly uses a function call syntax that is not applicable here.
