I thought NodePort was less secure than LoadBalancer, not sure about this approach.

Wait, did they really specify the target port as 'tarport'? Seems like a typo.

Just a reminder, NodePort exposes the service on each node's IP.

I remember creating a service YAML file for a project, but I’m uncertain if I need to include the `type: NodePort` in the spec section or if it’s optional.

I believe the service needs to have a selector that matches the deployment labels, but I might be mixing that up with another topic.

I practiced a similar question where we had to expose a service using NodePort, but I can't recall the exact syntax for the `kubectl expose` command.

I think I remember needing to edit the deployment to add the port specification, but I'm not sure if I need to use `kubectl edit` or if there's a better way.

I'm a little confused about the difference between using `kubectl expose` and creating a service YAML file. I'll need to review the options and decide which approach makes the most sense for this task.

Okay, I've got a plan. First, I'll use `kubectl get deploy front-end` to inspect the existing deployment. Then I'll edit the deployment to add the port specification. After that, I'll create the new service using the provided YAML example.

Hmm, I'm a bit unsure about the exact syntax for the service YAML file. I'll need to double-check the Kubernetes documentation to make sure I get the formatting right.

Configuring TCP Insight on the Citrix ADM could be a good option, as that might provide more detailed insights into the connection patterns. But I'm not sure if that alone would trigger the alerts we need.

Okay, let me see. I think the key is to focus on the order of the steps. I'll try to visualize the process and see if that helps me identify the correct answer.
