Your question is Infrastructure as Code for Reproducibility. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How do you implement infrastructure-as-code to ensure environment reproducibility and stability?
Describe a practical implementation approach covering repository structure, configuration management, state handling, validation, deployment workflows, and rollback. Explain how you would keep development, staging, and production environments consistent while controlling changes and secrets.
