The Kubernetes API is commonly described as which type of interface?

• A. RESTful interface
• B. GraphQL interface
• C. CRUD interface
• D. SOAP interface

Answer: (C)

The interface is best described by how it manages resources through a standard lifecycle. In Kubernetes, you work with objects like pods, deployments, and services by creating them to declare desired state, reading them to observe current state, updating them to modify configuration or behavior, and deleting them to remove resources when they’re no longer needed. The API server exposes these capabilities over HTTP in a REST-like manner, with each resource addressed via a URL and HTTP verbs that map directly to actions: create uses POST, read uses GET, update uses PUT or PATCH, and delete uses DELETE. This CRUD pattern is what people rely on when they talk about interacting with the Kubernetes API, since it centers on the lifecycle of resources. While you’ll also encounter RESTful characteristics and additional operations like watching for changes, the core way you manage cluster state in Kubernetes is through CRUD-style interactions.
