Kevin,
Thanks for the piece of advice. I am clueless when my manager
ask me to fill up the test without providing the necessary
study material. Since I am not a wireless specialist and the
web content is not sufficient, my mind just go blank so I made
up my mind to try a luck posting here in group study.
I'm truly sorry and regret for what I had caused.
Thanks again, my sincere apology.
Regards,
Ryan

Having passed the wireless exams just a while back I don't think anyone can
really answer these questions for you. I can't remember a NDA but I'm sure
something was there to agree to.
I'm a bit concerned that you posted them. Although it is easy to copy them
I don't think that means you should post them publicly.
This particular exam - although it has to be passed by a "person", does not
give the "person" a qualification. The qualification goes to the Cisco
Reseller/Partner.
If you work for a Reseller/Partner you can go to the on-line learning site
where you can receive the courses that Cisco recommends. All that
information is there.
If you read this page: (requires CCO login)
http://www.cisco.com/warp/customer/765/partner_programs/specialization/wlan/
requirements.shtml
you will see where you can get the info to answer these questions.
I took all three courses - having a high speed internet connection helps.
However, the slides and audio can be downloaded. (the video is just a
talking head anyway......)
Although a bit lengthy, the courses allowed me to pass with no problems.
(that and having taught radio/antenna theory in the military)
Please do the correct thing and study for the exam instead of asking for the
answers. These are basic knowledge questions. If you can't answer them -
you shouldn't be selling it or designing wireless networks for clients.
