As the subject says, I failed the 640-863 this passed Tuesday and have registered to take it again this coming Monday (after waiting the mandatory 5 days). Without violating any NDA's, I'm wondering what I should expect for the re-test. I'm looking for insight from anyone who has previously failed a Cisco test and has retaken the exam. Was it similar to the first version? Should I expect the same questions? Similar, but not exactly the same?
