Interestingly, if you worked a lot with NoSQL systems, you could get 5/5 on that score. Although I worked a lot with SQL in past, I think good knowledge of only a NoSQL system (e.g. GAE Datastore) would give you enough understanding of how simple indexes are, and how to deal with them to pass this pure SQL test. Would like to hear a feedback from someone with only NoSQL experience after taking that test.
