> For this question you for example need to know that such cross-region snapshot functionality exists. Do they put services AWS doesn't have in the answers? I'm pretty sure they wouldn't since it would make themselves look bad. But yeah if they put in a lot of nonsense answers I agree it works to prove that the guy knows AWS, but I wont believe they do until someone proves otherwise. > Also conditions like "minimal cost" can make an obvious looking answer the wrong one if don't know details about the cost of the affected services. Not really, the only time you can make sweeping statements about "minimum cost" is when it is both minimal both in engineering hours and running costs. Therefore the solution with the least number of engineering hours spent will be the right answer.
