Title: All you need
Review: This book contains all the information pertaining to the 507 exam with no fluff and nothing left out. It doesn't read like a Stephen King novel, but it doesn't read like a dry technical tome either. I tried using CCNA for dummies but I consistently failed the practice exams I found online, so I purchased this book, and I scored a 924 on the exam. I recommend reading this book once cover to cover, and then rereading the OSI model chapter and other chapters you may have trouble with. I was lost much of my first way through, but everything fell into place the second time around. I'd also recommend doing all of the labs in the book with either a real router or a simulator. It's crucial to understanding the proper syntax of IOS commands. It's not necessary, but pretty helpful anyway. And practice with the CD-ROM test and every practice test you can find online. If you miss a question, it's most important that you know why you missed it. The test really isn't difficult if you know your stuff.
