Kubernetes and Cloud Native Associate (KCNA) — Question 101

Which authorization-mode allows granular control over the operations that different entities can perform on different objects in a Kubernetes cluster?

Answer options

• A. Webhook Mode Authorization Control
• B. Role Based Access Control
• C. Node Authorization Access Control
• D. Attribute Based Access Control

Correct answer: B

Explanation

Role Based Access Control (RBAC) is designed to offer precise permission management, allowing administrators to define what actions users and services can perform on Kubernetes resources. The other options, such as Webhook Mode and Node Authorization, do not provide the same level of granularity in control as RBAC does.
