How does "Pod-to-Pod" networking typically work across different nodes in a cluster at a conceptual level (the "Kubernetes networking model")?
Correct! Well done.
Incorrect.
The correct answer is B) The Kubernetes networking model requires every Pod to get its own IP and that Pods can communicate with any other Pod across nodes without NAT, with the CNI plugin implementing this flat (or routed/overlay) network across the cluster
Correct Answer
The Kubernetes networking model requires every Pod to get its own IP and that Pods can communicate with any other Pod across nodes without NAT, with the CNI plugin implementing this flat (or routed/overlay) network across the cluster
A core Kubernetes networking requirement is that Pods are addressable by their own IPs across the entire cluster without NAT; CNI plugins implement this via various mechanisms (overlay networks like VXLAN, or direct routing with BGP).
