Not that it makes those questions worth putting on a test. but I took Microsoft's MCSA/MCSD tests last year and while some questions are "easy to look up", the tests are proctored and you're not allowed to open ANY apps during the test. You're also not allowed to have any devices within reach (which they verify via webcam).
if questions are easy to look up then i don't need to memorize thrm just to pass a test. that is the whole issue with certifications.
if the learning path would be such that you work with a system until you have enough experience that you can pass the test without having to learn for it, then that would be valuable, but the problem is that the certificate does not verify your experience. it verifies that you memorized certain facts without being able to tell how you did that.
