Acknowledgments

When James Manly and Allan Johnson reached out to me in March 2020 to see if I would be interested in authoring a 31 Days book for the ENCOR 350-401 certification exam, I was initially a bit daunted because of the breadth and depth of the blueprint, but after spending the previous year working with Learning@Cisco to develop material for ENARSI, ENCOR, and ENSLD courses, I felt I could take up the challenge.

As the 2020 global pandemic hit, writing a book from home turned out to be the ideal project for me and my family, so my first thanks must go to both James and Allan for trusting me with this contribution to the 31 Days series.

My technical editor, Akhil Behl, kept me on my toes and was quick with his comments, ensuring that we could get this book out to you quickly.

My development editor, Ellie Bru, did a fabulous job of cajoling and encouraging me throughout the writing process. She is a gem; Cisco Press should count themselves lucky to have her. My thanks also go out to Mandie Frank and Kitty Wilson, who ensured that the book you now hold in your hands looks good and reads easily.

I think I’ve developed a reputation at Cisco Press for being a bit difficult when it comes to choosing the photo for the cover. Thank you to Chuti Prasertsith for his patience as we came up with the final design you now see.
