Question
📝 **Question:** Default K8s pod-to-pod connectivity? 📋 Pick the right answer. 💡 **Hint:** Re-read the theory above if unsure.
A
Blocked by default — kube-proxy denies cross-namespace traffic until an explicit `allow` rule is added per workload.
B
Open — every pod can reach every other pod. NetworkPolicy must be explicitly added to enforce isolation.
C
Same as Docker — pods on the same node share a bridge; cross-node traffic only works after explicit Service exposure.
D
Per-namespace isolation — pods inside one namespace see each other but cross-namespace traffic is denied by default.
