That is a good question. The only concern would be reachability. If you have external networks outside of the OSPF domain (type 5 LSAs) then you will not have reachability to them because the NSSA does not know about them. In this case, a default route would be needed because you have RIP domains beyond the OSPF domain.
You basically have two options, no-summary or default-information-originate. Since no-summary is really not needed, the other should be used. Now it may not matter...you may ask the proctor for clarification. I wouldn't necessairly call the no-summary option wrong, its just of matter of recognizing when you need it or not.
