This review is from: CCNA Security 640-554 Official Cert Guide (Kindle Edition)
Got this one on Kindle, very good read while on the go. I spend a lot of time travelling, reading this text on my Nexus 7 with Kindle software is great. Book is well organised and written by one of the best Cisco teacher I have have ever seen - Keith Barker. His way of explaining things is almost perfect - almost because there is always something that require extra attention and checking other sources. I enjoy reading every chapter of this book. It is great help in my CCNA Security exam preparation...
