HashiCorp Certified: Terraform Associate — Question 210

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

Answer options

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

Correct answer: D

Explanation

The correct answer is D because it correctly references the variable using the var() syntax, allowing the module to access the value of num_servers. Option A is incorrect as it uses an improper syntax for accessing the variable. Option B is not valid in this context as it uses a command substitution syntax rather than a variable reference. Option C fails to use the var() function, which is necessary for module input assignments.
