I would like to thank my family for all their continuous support and encouragement, and especially my father, Asghar Bhaiji, for his wisdom. Last but not least, I reminisce about my mother, Khatija Bhaiji, whose love is ever shining on me.
I would like to especially thank the technical reviewers, Nairi Adamian, Gert DeLaet, and Kevin Hofstra, who have done an amazing job in contributing to this book. Their valuable feedback and efforts to research each topic are greatly appreciated in the accomplishment of this project.
I extend my sincere gratitude to Brett Bartow and the entire development team—Betsey Henkels, Dayna Isley, Barbara Hacha, San Dee Phillips, Chris Cleveland, and members of the Cisco Press team working on this project, whose expert guidance has been a determining factor in the completion of this book.
I would like to take this opportunity to thank my manager, Sarah DeMark, the leadership team of Learning@Cisco group, and my colleagues at Cisco for their support in writing this book and every other project. I have benefited greatly from working with them and am honored to be a member of this team.
Finally, I would like to thank you, the reader of this book, for helping me to make this book a success.
