What is Infrastructure as Code?
WHAT IT TESTS: the case for declarative infrastructure. OUTLINE: IaC defines infra in version-controlled files, giving repeatability, peer review, and drift-free consistency, unlike error-prone console clicks. RED FLAG: calling it mere scripting.
WHAT IT TESTS: whether you understand why infrastructure should be code, not clicks. ANSWER OUTLINE: IaC describes infrastructure in machine-readable, version-controlled definitions that a tool provisions automatically, usually declaratively. Benefits over manual console work: repeatability so identical environments are recreated reliably, version history and peer review, consistency that eliminates drift and snowflake servers, automation, and self-documentation. RED FLAG: equating IaC with ad hoc CLI scripts or ignoring state and drift.
