Not sure what your interviewer was expecting on this.

The only thing i can recall is if because of some reason your cognos server gets restarted and if services startup type is set to "Automatic" then your cognos service will go down and come up automatically.

I don't remember any other case where I was fortunate enough that my Cognos environment came up automatically.  :P :)

Because you've got a scheduled overnight task that stops and restarts the Cognos services?

(We actually did this for a few months, while on 8.3, due to some problem of instability which I've long since forgotten).

may also be cause by memory outage. If too many reports are running at a given time together with other services, cognos service might got down and if your service is set to start automatically it will restart or if the service is set to restart for a particular number of times after failure. hence, i can see the closest would be that it is scheduled to do so, can be for many reasons.
