I understand that is a requirement for partner status. You may find details in PEC or there may be a course however there is little training for wireless available in the way of reading materials. There are some CCNA Wireless books and CCP Wireless quick learning modules.
Your manager or Cisco contact may be able to advise of options locally but I woould look at PEC first.
Found it, I had to go to the Gold requirements and then there is a link there, that eventually takes you over to an online course for the lifcycles
That link doesn't appear to work unless you are already logged into Element K's site. You can also go to PEC and search for "Cisco Lifecycle Services Advanced Wireless v2.0."
Yes, the PEC should have training videos for the exam. Block off half a day or so on your calendar to watch the videos and take notes. Then take the exam directly afterwards while it's fresh in your mind.
Since it's a test that you take online, it's essentially an open book exam.
