The CCNA exam(s) require a near-perfect fluency in subnetting. Success requires speed and accuracy in answering the many questions you will see on this topic. The key to this level of fluency is practice -- you must work at your skills until they become second nature. The section excerpted here discusses binary and hexadecimal numbering systems as compared with the more familiar decimal system. It also gives you helpful subnetting charts and teaches you how to construct them for yourself.
CCNA Exam Cram 2, Second Edition is a concise, comprehensive study aid, perfect for anyone preparing for the CCNA exam. This updated edition to the popular Exam Cram will keep you up to date on the latest version of the exam, while continuing to provide you with specific, targeted explanations of the concepts and commands that you will find on the actual CCNA exam.
