Looks good to me, but I’d test it first before running in production.

This is a classic mistake, always double-check your grep patterns!

Surprised they didn't mention the need for proper permissions on /opt/KUTR00101/bar.

Totally agree, it should be 'file-not-found' instead of 'unable-to-access-website'.

That command won't catch 'file-not-found' errors.

I think the command should be `grep 'file-not-found'`, but I’m not completely confident. I hope I don't mix it up with the other error messages we studied.

I practiced something similar where we had to filter logs, but I feel like I might confuse the error message. Was it 'file-not-found' or something else?

I think I remember that we need to use `kubectl logs` to get the logs, but I'm not sure about the exact error message to grep for.

I definitely recall writing logs to a specific path, but I can't remember if we need to use `>` or `>>` for appending.

Based on my experience designing flows, I think the best approach is to use the data pill to bring in the necessary record data. Option D seems like the right choice here.

Wait, I'm confused. Isn't the patient's name one of the most important things that has to be on the label? I'm not sure about this one, I'll have to re-read the question carefully.
