+22Namespaces are used in Kubernetes for isolating resources. However, this does not affect networking. For network isolation you would need to create network policies in order to segregate workloads.

+22The Answer is TRUE!
Kuberenetes namespaces will not stop net work traffic. For that you have to implement Network Policies and leverage a CNI (Container Network Interface) that supports Network Policies.
For a deeper explanation, as always, the official Kube docs are your friend:

If you want to have some fun and play around with Netpol in minikube here is a great post to try:
