I've been learning a lot with this book, but sometimes I find tiny grammar errors or some content misleading information that makes me feel worried about some topics. E.g.: Answers to the “Do I Know This Already?” quiz: -Page 96 states that the answer for question 8 is A, B, D. However, in appendix A, answers to chapter 5 quiz, states that the answer for question 8 is A, B,C (which is the right one based on chapter 5). Nothing is perfect, I hope Cisco and Pearson could see this kind of observations in order to make the book even better. Besides that, it's been an excellent investment for my professional career. I highly recommend it.
