For how long is the Kubernetes API guaranteed to be backward compatible following a release?

• A. Indefinitely
• B. One year
• C. Six months
• D. Two years

Answer: (B)

The main idea is that Kubernetes guarantees backward compatibility of the API for about one year after a release. This means that for roughly 12 months following a release, the APIs you use in manifests and client code should remain stable and accepted by newer clusters within that window. This gives operators time to upgrade and migrate workloads without having to rewrite API usage immediately. After that period, deprecated APIs may be removed or changed in ways that require migration to newer API versions. So the correct choice reflects a one-year window, not an indefinite period or shorter/longer spans.
