I think you might need to filter the results more specifically.

This seems straightforward, but what if there are multiple pods with high CPU?

Wait, is the pod label really `cpu-user`? Thought it was `cpu-utilizer`.

Totally agree, that's the way to go!

Just use `kubectl top` to check CPU usage!

I think the command to write to the file is right, but I’m not sure if we need to include the pod name dynamically or just echo a static name.

I feel like I practiced something similar, but I can't recall if we needed to sort the output to find the highest CPU pod. Should we use `sort` or something?

I remember a practice question where we had to filter pods by labels. I think we should use `-l name=cpu-utilizer` instead of `cpu-user`.

I think we need to use `kubectl top` to check the CPU usage, but I'm not sure if the label is correct. Was it `cpu-utilizer` or something else?

This seems straightforward enough. I'll just run `kubectl top pods -l name=cpu-utilizer` to get the CPU usage for the relevant pods, find the one with the highest usage, and then use `echo` to write the name to the file. Should be a quick and easy one to knock out.

Okay, I think I've got a plan for this. First, I'll use `kubectl top pods -l name=cpu-utilizer` to get the CPU usage for all the relevant pods. Then I'll sort that output to find the pod with the highest usage, and finally I'll write the name of that pod to the file using `echo`. Hopefully that'll do the trick!

Hmm, I'm a bit confused by this one. I know we need to find the pod with the highest CPU usage, but I'm not sure how to do that exactly. I'll probably start by trying `kubectl get pods -l name=cpu-utilizer` to list the pods, then try to figure out how to get the CPU usage for each one.

This looks like a straightforward task to find the pod with the highest CPU usage and write its name to a file. I'll start by using the `kubectl top` command to get the CPU usage for all pods with the `name=cpu-utilizer` label, then I'll pipe that output to `grep` to find the pod with the highest usage and write its name to the file.

Okay, let's see. The question is asking about the minimum number of compute nodes, so I'll need to think about the minimum requirements for running this engine. I'll go with my best guess.

Got it, that makes sense. The $3,000 cash is considered "boot" and reduces the basis of the new van. I'm feeling pretty confident about this one now.

Hmm, I'm a little unsure about this one. There are a lot of options, and I'm not sure I fully grasp the nuances of DRM implementation. I'll need to carefully read through each choice and try to identify the top three risks. Wish me luck!
