Kubernetes and Cloud Native Associate (KCNA) — Question 50

Which statement about the Kubernetes network model is correct?

Answer options

• A. Pods can only communicate with Pods exposed via a Service.
• B. Pods can communicate with all Pods without NAT.
• C. The Pod IP is only visible inside a Pod.
• D. The Service IP is used for the communication between Services.

Correct answer: B

Explanation

The correct answer is B because, in Kubernetes, Pods can communicate with each other directly using their IP addresses without the need for Network Address Translation (NAT). Option A is incorrect since Pods can communicate with each other regardless of Service exposure. Option C is false as Pod IPs can be accessed by other Pods in the same network. Option D is misleading because Service IPs are primarily for accessing Services, not for communication between them.
