A cluster's CNI does not implement NetworkPolicy. What should an application developer expect after creating NetworkPolicy objects?
Select an answer to reveal the explanation.
Short Explanation
NetworkPolicies without a supporting CNI are like posted rules with no security guard—objects can exist, but packets won't be filtered. CKAD awareness: enforcement needs the network plugin, not the API object alone.
Full Explanation
NetworkPolicy resources are honored only when the cluster network plugin implements them. Without that support, creating policies has no traffic effect even though the API accepts the objects. The control plane does not independently filter Pod traffic, and creating a NetworkPolicy does not install a CNI.
