HashiCorp Certified: Terraform Associate (003) TA-003 — Question 100

The correct answer is C. Option C: Declare a node_count input variable for child module

Explanation

A Terraform module packages related resources into a reusable configuration with defined inputs and outputs. A child module is called by another module to reuse and encapsulate infrastructure configuration. An input variable parameterizes a module so callers can provide environment-specific values.
