As you probably know, I tend to be conservative about providing any information "in advance" that could give away crucial clues about the quiz.
Having said that, however, I am inclined to support the above idea. Basically, the idea here would be that many developers are not yet working with the latest versions of Oracle (in this case, 11g). Which puts you at a tremendous disadvantage when the clock starts ticking and then you are confronted with a version with which you do not have much, if any, familiarity.
And offering as an advance "clue" that we'll be working with 11g is a rather broad hint that doesn't really give away too much information.
