Question
Which statement about the Kubernetes network model is correct?
Options
- APods can only communicate with Pods exposed via a Service.
- BPods can communicate with all Pods without NAT.
- CThe Pod IP is only visible inside a Pod.
- DThe Service IP is used for the communication between Services.
Explanation
The Kubernetes networking model ensures that all pods can communicate with each other directly using their pod IPs without Network Address Translation (NAT).
Common mistakes.
- A. Pods can communicate directly with other pods using their IP addresses; Services provide an abstraction and load balancing layer, not the sole means of communication.
- C. Pod IPs are routable and visible throughout the cluster, allowing other pods and nodes to directly address them for communication.
- D. Service IPs are virtual IPs used by client pods to access a logical service, which then routes traffic to backend Pod IPs; the Service IP itself is not used by Services to communicate with each other directly as clients.
