More sysadmin / troubleshooter focused person here, and I love this sort of question. It also brings out people who will throw out things like "do a network capture". Then you either get the "well, send it to the network team!" answer or the (much more desirable) "look for X, Y, Z, or something weird in N...".
No, I'm saying that it's used as a blowoff answer for something that sounds important because it's outside of what one in said job would normally do, but when asked about it (to see how generalist the person is) they wave it off as something for another person to handle.
