I successfully went into, and passed my #KCNA exam. I actually bought the exam coupon last December and just hadn’t got round to doing the exam.

I ended up walking away with only 3 questions wrong. Two I wasn’t sure of anyway, so I’ll assume I got those wrong. The third however, I’m not sure which one I got wrong.

However there was one question in there which technically had no correct answers selectable. The question was this:

Which of the following is a valid Kubernetes pod restart policy?

• on init
• on update
• on startup
• on failure

None of the above are, strictly speaking, correct. It should be OnFailure and not on failure — see the Kubernetes docs.

I picked on failure as that is the closest to being correct.

I’ll be pretty pissed if they marked me wrong on this question.
