A few days ago when I started planning to study for 3V0-622, I was concerned at the lack of materials. After some research I found it was mostly just a lack of recently published material and that much of what was useful when studying for VCAP5 is also useful for VCAP6. Now I have a list of all the resources listed below. I've downloaded over 170 MB of PDFs from the links listed below which amount to thousands of pages of materials along with several books. So I'm now faced with the opposite problem I started out with which is an overwhelming amount of materials.
I've already passed the VCAP-DCA so I'm pretty well versed in administering VMware products, but I haven't done any design before. I want to spend as much time as is necessary to pass this test but I don't want to study in too much excess.
I am hoping that some people who have passed this test can give me an idea of how long it took to study for this and about how many materials you ended up needing to cover.
