1 What is the primary purpose of Infrastructure as Code (IaC) in DevOps?
Correct Answer:
B
Explanation: Infrastructure as Code (IaC) allows teams to manage and provision computing infrastructure through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools.
