I think it’s important to test the policy after applying it!

Wait, can NetworkPolicies really limit traffic like that? Sounds too good to be true.

I feel like I’ve seen a question like this before, but I’m a bit confused about the syntax for the YAML. I hope I can recall it under pressure!

I think I need to double-check how to reference the specific pods in the namespace. I hope I don't mix up the labels!

This seems similar to that practice question where we had to restrict traffic between different services. I think we need to define ingress and egress rules.

I remember we practiced NetworkPolicies, but I'm not entirely sure how to specify the pod selectors correctly for this task.

Hmm, I'm a bit confused about the differences between the options. I'll need to carefully read through each one to understand the nuances.

Hmm, I'm not totally sure about this. I know the daily scrum is important, but I can't quite remember the exact goal. I'll have to think this through carefully.

Alright, time to put on my network security hat and make sure that ckad00018-newpod pod is as isolated as a monk in a monastery.

This is a piece of cake! Just a quick application of the network policy, and I'll have that pod locked down tighter than a clam's backside.

Hmm, I wonder if the web and db pods are in the same namespace as the ckad00018-newpod pod. Gotta double-check that before implementing the network policy.

The solution looks straightforward. I'll apply the network policy to the ckad00018-newpod pod in the ckad00018 namespace to restrict traffic to the web and db pods.
