This seems too simple, I feel like there's more to it.

Nice, but what if there are multiple pods with high usage?

Wait, is that the right label? Shouldn't it be `cpu-utilizer`?

Just use `kubectl top` to check CPU usage!

I think the command to find the pod with the highest CPU usage is straightforward, but I’m a bit confused about how to extract just the pod name for the output file.

I feel like I should be able to write the output to the file, but I can't remember if we need to use `>>` or just `>` for appending.

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 `cpu-user`?

I remember practicing a similar question where we had to filter pods by labels. I hope I can recall the exact command for this one.

Hmm, I'm a bit unsure about this one. The question is asking about a specific value in a report, so I'll need to make sure I understand the context and the possible meanings of that value.

This seems like a straightforward question. I'd go with option C - explain that it's not an IT issue and they need to speak to someone else.

I think I know the answer to this one. Creating a context filter for a crosstab report using a dimensional data source changes the rows and columns, not just the measure values.
