Comments: This is the only book you need to pass the CCNA. With this textbook, a practice test (from MeasureUP, CCPrep, or Ccxxproductions), and some eLab time from CCPrep, you will easily master the material that will result in the CCNA. You don't need to spend two years in a Cisco Academy, reading the book through an authorized CBT. This book retails for $60. A good practice test is under $100, and some eLab time is less than $100. For less than $300, you can earn the CCNA. But, having said that, make sure before you tackle the CCNA that you understand the principles covered in the A+ and Network+ certifications.
