I think we should use the `podSelector` to restrict access, but I can't recall if we need to include any specific ports or protocols.

I feel like I might confuse the namespace settings. Do we need to specify the namespace in the NetworkPolicy?

I remember practicing a similar question where we had to set up ingress rules. I hope this one is just as straightforward!

I think we need to define the pod selector correctly to match the allowed Pods, but I'm not entirely sure about the syntax.

Hmm, this seems straightforward. I'd go with HttpSession objects and a database to store the cart items.

Analytics Builder could be a good choice, but I'm not as familiar with that tool. I'll need to review the capabilities of option C to see if it fits the requirements.

Once you set up the NetworkPolicy with the correct namespaceSelector, only the specified Pods will be able to connect to users-service.
