Kim Wimpsett was the development editor of this Sybex CompTIA series as with the previous three. Thank you, Kim, for your patience and kindness and for working so hard on this book with me once again, and I look forward to any book that has Kim on the editorial board.

Kenyon Brown was the acquisitions editor for this book. Thank you, Kenyon, for making this fourth book in the series a reality.

In addition, Christine O'Connor was an excellent managing editor, and she worked hard to get the book done as quickly as possible. I have worked with Christine for well over a decade and I am always very pleased when I hear that she will be working with me on yet a new project. Barath Kumar Rajasekaran, who is a content refinement specialist, did a great job of keeping this book on track with both authors; thank you!

As with Kim and Christine, I have also worked with Judy Flynn for more than a decade. She knows my work so well she can provide some technical advice and also understands how I write and can wordsmith right along with my tone and voice. Thank you, Judy!

Troy McMillan literally hashed and rehashed each topic in this guide with me at all hours of the day and night. Thank you, Troy, yet again!

Todd Montgomery really came through when I was in a tight spot and helped me finalize Chapters 21–25 as well as a few other chapters. Thank you, Todd—you're a lifesaver!

Chris Crayton tech edited and reviewed each topic in this guide, scrutinizing the material until we both agreed it was verifiably solid. Thank you, Chris!
