The book is filled with features that help you master the skills to implement appropriate technologies to build secure networks based on the Cisco Systems SAFE Blueprint. This book was developed in cooperation with the Cisco Internet Learning Solutions Group. Cisco Press books are the only self-study books authorized by Cisco for CCSP exam preparation.Cisco and Cisco Press present this material in text-based format to provide another learning vehicle for our customers and the broader user community in general. Although a publication does not duplicate the instructor-led or e-learning environment, we acknowledge that not everyone responds in the same way to the same delivery mechanism. It is our intent that presenting this material via a Cisco Press publication will enhance the transfer of knowledge to a broad audience of networking professionals.Cisco Press will present study guides on existing and future exams through these Exam Certification Guides to help achieve Cisco Internet Learning Solutions Group's principal objectives: to educate the Cisco community of networking professionals and to enable that community to build and maintain reliable, scalable networks. The Cisco career certifications and classes that support these certifications are directed at meeting these objectives through a disciplined approach to progressive learning. To succeed on the Cisco career certifications exams, as well as in your daily job as a Cisco-certified professional, we recommend a blended learning solution that combines instructor-led, e-learning, and self-study training with hands-on experience.
