I thought network policies only worked within the same namespace?

This is a classic use case for network policies!

Wait, can we really restrict by labels across namespaces?

Agree, but what about pods in other namespaces?

Sounds straightforward, just need to set the right selectors.

I believe we have to specify the pod selector for nginx-test and then set the ingress rules correctly. I hope I remember the syntax right!

I’m a bit confused about how to apply the network policy after creating it. Do we just use `kubectl apply` with the YAML file?

This question feels similar to the practice we did on network policies last week. I think we need to use ingress rules to allow traffic from the specified pods.

I think I remember that we need to define the pod selector and namespace selector in the network policy, but I'm not entirely sure how to structure it.

This seems like a straightforward question about the foundations of delivering great customer service. I'll carefully read through the options and choose the one that best fits the description in the prompt.

Hmm, I'm not sure about this. I'll have to review the regulations around transfers to high-risk countries.

Ah, I see. Terminating and relaunching the instance could also be a good approach, as that would give us a fresh start. I'll have to weigh the pros and cons of each option.

I'm not totally sure about this one. I know revenue bonds are different from general obligation bonds, but I'm not confident I fully understand the implications for repayment. I'll make an educated guess, but I may need to review this topic again before the exam.
