In a new namespace with healthy Pods and no NetworkPolicy objects, what is the default Pod-to-Pod connectivity posture?
Select an answer to reveal the explanation.
Short Explanation
Out of the box, Kubernetes is a friendly open office—Pods can chat until someone hangs NetworkPolicy doors. No policies means no extra isolation. Default-deny is something you add on purpose.
Full Explanation
Kubernetes networking is open by default: Pods can reach other Pods (subject to IP routing/CNI) until NetworkPolicies select them and restrict ingress and/or egress. There is no built-in namespace default-deny without policies. LoadBalancer Services are an exposure mechanism, not a prerequisite for Pod-to-Pod traffic.
