    Dont Recommend

    I have tried to read this book but really cant get into it. Some of the ways he explains are difficult to understand & these are some of the I already know because I have prior knowledge of some network fundamentals. The author expresses to much about things that are going to be discussed in later chapters which is annoying. I see a lot of great reviews for Mike's comptia books so Im going to check that one out.
