Chapter 11. Sample Exam 640-821

Do not read Chapters 11 to 16 until you have learned and practiced all the material presented in the chapters of this book. These chapters serve a special purpose: They are designed to test whether you are ready to take your CCNA exams. Chapters 11 and 12 deal with exam 640-821, Chapters 13 and 14 deal with exam 640-811, and Chapters 15 and 16 deal with exam 640-801. Each exam is followed by an answer key and brief explanation of correct answers along with an explanation for why the other answers are incorrect. Reading these chapters prior to other chapters is like reading the climax of a story and then going back to find out how the story arrived at that ending. Of course, you don't want to spoil the excitement, do you?
