Which of the following is an example of infrastructure as code?

• A. Cloned virtual machine images
• B. Change management database records
• C. Versioned configuration files
• D. Docker files

Answer: (C)

Infrastructure as code means describing the desired state of your infrastructure in text files that you can version, review, and apply with automation tools. Versioned configuration files are a perfect fit because they capture all the settings for resources (like servers, networks, and storage) in a human‑readable, machine‑driven form that can be tracked in source control and applied to recreate environments consistently.

Cloned virtual machine images are concrete artifacts, not a description of the infrastructure you want. Change management database records describe human processes around changes, not the infrastructure itself. Dockerfiles define how to build container images, which is related to deployment environments, but the classic infrastructure‑as‑code emphasis is on declaring and provisioning infrastructure resources via configuration files that tools like Terraform use.
