In the movie Divergent, are the phase 2 testing expectations different than the Kobyashi Maru?

I.e. unlike the Kobayashi Maru which is setup as a "no-win" scenario, is the expectation that all Dauntless initiates should have a solution within the phase 2 test if the initiate simply practices enough? Hence, any initiate that does NOT find a solution can summarily be cut?

However, Four claims that is not valid. That each initiate has to "find some tool, some method to survive." If so, it begs the followup question, what determines what "solution" options exist within the test for each individual and what is considered "valid" for a Dauntless."

I have not read the book, so would be interested if there is more information not available in the movie on how the Test actually works.

Thanks.
