Kubernetes supports multiple authorization modules including ABAC and RBAC. What is another mode it supports?

Service account mode
Webhook mode
Client mode
Identity mode

The correct answer is: Webhook mode

Kubernetes indeed supports multiple authorization modules to manage access control, and webhook mode is one of the flexible and dynamic methods it offers. In webhook authorization mode, Kubernetes delegates authorization decisions to an external service via HTTP requests. This allows for dynamic and contextual authorizations based on custom logic implemented in the external service, making it ideal for organizations with complex access requirements. Webhook mode can integrate with various authentication providers and adapt to changes in access policies without needing to reconfigure Kubernetes, providing a powerful way to handle authorization while leveraging existing systems and processes. In contrast, other options such as service account mode, client mode, and identity mode either do not accurately describe an existing Kubernetes authorization method or represent more limited approaches compared to the extensibility offered by webhook mode.
