More to the point, however, I do think you will be better served updating your library to prepare for the new exam. The OSI has not changed, but there are some updated topics that will not be present in your old books such as VoIP, wireless technologies, and the SDM GUI interface. If you are looking for a recommendation, I am biased to recommend the CCNA Exam Prep 640-802 which I co-authored.
