Coming from IPO,BCM,Cisco world, it took me a while to remember all the SV8100 cards and which one can be combined together . Lots of question on them as I remembered when I took the test last July.
Yes, the test is timed but you should do fine as it is really not that hard. I practiced a lot on my SV8100 lab as I just like to break and fix to reinforce what I learned via the online training
The voice mail UM8000 is way too easy to pass , IMHO .
