Question

A platform engineer is validating whether a newly built Kubernetes cluster conforms to the Kubernetes networking model. They want to confirm the fundamental rule that any CNI implementation must satisfy for the cluster to be considered compliant. Which statement correctly describes a core requirement of the Kubernetes networking model?

Accepted Answer

Every Pod must be reachable by every other Pod across all nodes without using NAT, and each Pod sees the same IP that others use to reach it.

Answer

Pods on different nodes must communicate exclusively through a NodePort Service to reach each other.

Answer

Each node must run kube-proxy in IPVS mode so that Pod-to-Pod traffic is address-translated between nodes.

Answer

Pod IP addresses must be assigned by the API server from a single shared range so that all Pods on a node share one IP.
