Luis Cifer from Hong Kong – 12 02 2012, 7:20 AM Report Spam Exam C – Q534 options of the original 802.11 standard I reviewed the original standard and there is no mention of the channel bandwidth. however, in the quick study guide it mentions that FHSS uses almost 80 1Mhz channels in the US. and then in the QRFHSS is still described in the original 802.11 protocol, but another technique was preferred and adopted by all 802.11 networks:Direct Sequence Spread Spectrum. Instead of small channels and a jumping sequence, the information is sent over a wider channel.This channel is 22 MHz wide (if the center frequency is 2.412, this channel spans from 2.401 GHz to 2.423 GHz) and does notmove (no hopping, which is why the sequence is said to be direct instead of hopping). Then, over this 22 MHz channel, severalbits of information are sent in parallel. So I think it should be 22 Mhz instead of 20 Mhz imalexis from Malaysia – 11 09 2012, 4:55 AM Report Spam passed the exam today 9 11 2012.

Benny from Australia – 09 02 2012, 11:21 PM Report Spam I took the exam on 31/08/2012. Questions still very relevant. 74 questions in the exam, all Multiple choice questions were in here. There may have been 3 drag and drops that were not, but nothing too hard. Also there were about 4 questions where you had to review switch config and WLC screen config and identify why things wouldn't work. It's easy if you studied, so obviously Adren didn't. Passed with 978, meaning only 1 or 2 wrong. So annoyed about that too! adren from Russian Federation – 08 31 2012, 4:12 PM Report Spam The dumps are realy out of date! There are lot of new questions.
