Kubernetes and Cloud Native Associate (KCNA) — Question 31

Which statement about Ingress is correct?

Answer options

• A. Ingress provides a simple way to track network endpoints within a cluster.
• B. Ingress is a Service type like NodePort and ClusterIP.
• C. Ingress is a construct that allows you to specify how a Pod is allowed to communicate.
• D. Ingress exposes routes from outside the cluster to services in the cluster.

Correct answer: D

Explanation

The correct answer is D because Ingress specifically manages external access to services within a Kubernetes cluster, routing requests to the appropriate services. Options A, B, and C are incorrect as they misrepresent the role of Ingress; it is not merely for tracking endpoints or a Service type and does not directly specify intra-Pod communication.
