Please accept my apologies if this has been addressed in another post, having searched I've been unable to find an answer to my question.
I'm a little confused as to which is the official study guide for CWNA & CWSP. When I took my CWNA exam I had 2 choices - the 'CWNA Certified Wireless Network Administrator Official Study Guide' published by Osborne, or the 'CWNA Certified Wireless Network Administrator Study Guide' (notice the missing 'Official') published by Sybex.
Having now made the decision to take my CWSP exam, I've searched for the PW0-204 update to the Osborne published PW0-200 book (which I also have) but all I can find is the equivalent by Sybex. Am I to understand that the Sybex book is now the de-facto study guide?
Any advice on this would be appreciated.
