Most Helpful Customer Reviews on Amazon.com (beta)
For example, he comes off as condescending in some paragraphs, using terms like "obviously". His explanation of IPSec transport and tunneling modes is confusing and seems to be explaining the same thing: "transport mode creates a secure tunnel between two devices end to end", and "in tunnel mode, the tunnel is created between two endpoints".
In the chapter on wireless, he promises to explain modulation techniques such as OFDM and DSSS, but doesn't. He makes crucial mistakes in the chapter on "Authentication and Access Control" by confusing symmetrical and asymmetrical public keys. On page 387 he writes: "When the keys at each end are different, it is called symmetrical or public key." That is wrong. It is asymmetrical keying if the keys at each end are different.
The early chapters don't offer much in the way of definition or context. Terms like "contention media-access" and "ethernet segment" will be thrown at you without any explanation.
Some of the review questions don't make any sense. For example, one of the answers for a chapter 5 question reads: "Any two or more devices the switch connects have are capable of causing a collision with each other." Another question refers to Hubs, Repeaters, NIC's, and Switches as "terms", rather than devices or equipment.
Overall, if you are bright enough, or experienced enough, you'll be able to overlook some of these problems and the book will teach you something. Otherwise, I'd recommend other Network+ study guides.
Just like the last edition, this book is well written and clear. It's all too easy to make technical writing boring, but I think author Todd Lammle worked hard to make his writing accessible and readable. He's clearly a networking expert. This is not to say it's elementary. You will need to have a fair understanding of networking, or at a least technical aptitude, to make sense of it. But that's what you would expect when studying for a technical certification.
I've also got to praise the book for few typos and errors. This is also something that's not too common in the fast world of technology publishing. Finally, the illustrations and diagrams in the book provide an excellent way to understand the concepts.
Unfortunately, you get less from this book then you do with the last edition. The last edition had the entire PDF of the textbook with it. I enjoyed reading it on my laptop and being able to search for specific topics. This newer book doesn't even include a CD anymore.
In fact, much of the features advertised on the cover aren't even included in the book. The "custom test engine" and "electronic flashcards" must be downloaded from the website. Plus, you must "register" to access it. What if this content is taken down from the web server in the future?
Strangely, one of the items that you must download is the glossary. It's not in the hard-copy book at all. That's very inconvenient.
One other thing that annoyed me was that the book advertises two "full-length" practice exams. In reality, each practice exam is just half (50 questions) of what makes up a real exam. This is disappointing because practice questions are very helpful in preparing for the exam.
If you're wondering, I did pass the Network + certification after my first try after reading this book. I also studied the "Network + Cram Exam". I would recommend studying from at least two books in a concentrated time-span for any CompTIA exam. It helps to reinforce your knowledge and the authors explain concepts differently. Also, make sure you understand all of the practice questions.
Lammle's book was my primary study resource. I read it cover-to-cover and took notes like a madman.
I also hunted and pecked my way through Mike Meyers Network+ All-In-One, as well as the ExamCram Network+.
I hit the Lammle book the hardest for one reason -- Networking education is his wheelhouse. His explanation of subnetting is concise and beautifully done. That alone is worth buying the book for.
However, if I had to offer one criticism it would be that Lammle's practice exams were a bit too soft.
The Mike Meyers book had better test questions and better artwork -- diagrams, graphics, etc.
If you can afford both, get them. The ExamCram book was also helpful in narrowing down what to memorize in the last week of studying.
I spent two months prepping for the test. I already have my A+ so I knew what to expect from a CompTIA exam.
I found the test to be challenging. Others have written in their reviews that they waltzed right through it. That was not my experience.
Best of luck.
