I just used his book, in conjunction with other materials, and took the ICND1 exam. I just barely did not pass, so i have to re-take it. Not sure about your book, but mine came with a Boson CD that contained Practice questions. I found those very helpful. Had i not used those to prepare, i feel that i would have failed miserably. the book i was issued is also 2nd edition, and i believe that is the most current.
