I’d argue that dealing with any high criticality operational incident is like an in person exam (maybe even the most difficult kind, the open book one) if you are the one responsible for fixing it. Everyone is looking at you, you have time pressure to solve it ASAP and you can’t afford the time to dig through all the docs on the spot. So there’s at least some similarity with some real life situations.
