My famous Binary, Subnetting, and Summarization Mastery Workbook has been fully updated for 2019 and the latest versions of the CCENT, CCNA, Network+, and CCNP exams! Whether you're studying for a Cisco or CompTIA certification exam, or you need to sharpen your subnetting creation and troubleshooting skills, this is the book for you. I'm Chris Bryant, "The Computer Certification Bulldog" (and CCIE #12933), and I've created this fully-illustrated workbook to give you the tools and the practice you need to nail any subnetting or binary-based question on any Cisco or CompTIA certification exam -- and to succeed with subnetting in real-world networks. And, of course, I'll teach you how to troubleshoot someone else's subnetting! You need no prior experience with binary or subnetting to use this book, as I've written it for you in a structure that will allow you to master the fundamental skills of binary and subnetting before moving on to the more complex subnetting questions. I show you exactly how every single answer in this book was achieved, so you'll have no hesitation on exam day when it comes to subnetting and binary conversions.
