CCIE certification is not always measure about your technical skills. It is also about your time management skills, selecting a best approach suit to you (there are unique ways of nailing the exam by different individual), your organizing skills & how do you cope with under pressure.
Specially in CCIE wireless track it is very hard to get the feelings about lab exam (since V2.0 release in Nov 2011) as very limited number of people have attempted it & shared their story. Best way to feel it is “go for the exam & judge yourself” where are you at ? But it will be a costly exercise (lab exam fee is over $ 1,500 & you have to travel USA, AUS or BELGIUM). So how do I know about CCIEW-v2.0 exam to better prepared ?
Apart from information available on Cisco official webpage for CCIE-Wireless (http://www.cisco.com/web/learning/le3/ccie/wireless/index.html) it is very limited information available from Cisco.
I found following document (CCIE-Wireless Techtorial -2012) available from “CiscoLive365″ is very useful to get more close feeling about v2.0. CiscoLive365 is the site where you can access most of Cisco Live event material for free (You have to register for CiscoLive365 first to view this). This particular document provide CCIEWv2.0 exam topics overview compare to v1.0. Few of the lucky guys who participated these sessions in US also blogged about this v2.0 exam. You can read few of them I found on internet on below URLs.
Another good source of information is the individual who has attempted the exam. I found below blog post sharing about their experience which is really helpful to know about CCIEW.
Sometime these stories are motivation factor to prepare yourself for the exam. So spend time to read those sort of stories while you are pursuing your CCIE wireless status & be focused.
