Cni — Certified Kubernetes Administrator (CKA) Practice Questions
The Container Network Interface (CNI) is a specification and plugin framework that Kubernetes uses to configure network interfaces inside pods when they are created or deleted. Kubernetes itself does not implement pod networking, so a CNI plugin such as Calico, Flannel, Cilium, or Weave must be installed to satisfy the flat network model requirement. CKA candidates are expected to know how to deploy a CNI plugin after initializing a cluster with kubeadm, recognize that NetworkPolicy enforcement depends on the chosen CNI, and be able to identify missing or misconfigured CNI installations when troubleshooting node NotReady states.
