Kubernetes and Cloud Native Associate (KCNA) — Question 132

Which mechanism allows extending the Kubernetes API?

Answer options

• A. ConfigMap
• B. CustomResourceDefinition
• C. MutatingAdmissionWebhookmechamsm
• D. Kustomize

Correct answer: B

Explanation

The correct answer is B, CustomResourceDefinition, as it allows users to define their own resource types in Kubernetes, effectively extending the API. Options A, C, and D do not facilitate the extension of the API; ConfigMap is for configuration management, MutatingAdmissionWebhookmechamsm relates to admission control, and Kustomize is a tool for managing Kubernetes resource configurations.
