CompTIA Network+ Certification Kit: Exam N10-009 7th Edition

Fantastic books

There are many errors and typos in the book. The errors are especially bad for the review questions as if you dont have experience they can really make you doubt your understanding. For a book of this price they really need to fix this and do better revision.

I like the book and got the 10% discount code for the exam voucher.

Please note that the review is only for the Study Guide and not the Practice Tests book. I purchased this as one more reference in my arsenal to study for the Network+ exam. The book is well organized and the author follows a logical method to introduce new concepts.Beware though. There are many typos and errors in the book. If you have some networking experience or you're understanding well the concepts, you will catch them. Otherwise, they can throw you for a loop.

Overall a good source of information but there is content that is straight up wrong or misleading. Key example being their explanation of collision domains: they cite there being 10 in an example when by their own logic it is 22.Another example is their explanation of multicasting. It is misleading because they explain that multicasting only sends data to certain hosts. Immediately after, they explain that it is instead sending it to every host, but only specific ones process it.These are just the ones I've caught, and while it's a good trove of information it forces the reader to not only consume the information but mistrust it.
