Self-Study Guides, which are based on Cisco courses for the related exams, provide essential foundation learning and thoroughly cover topics addressed in those courses. These books assume no prior knowledge of the subject matter and take a detailed approach to tutorial-based learning. Book elements within the Self-Study Guide Series feature real-world case studies, configuration examples, and chapter-ending review questions, making them useful on the job, in addition to exam preparation.

Exam Certification Guides help prepare candidates for Cisco certification exams. These books assume readers have attained the necessary learning foundation and experience for a certification test and are reviewing material before exam time. They include summary information that details critical information on key exam topics and a companion CD-ROM, which contains a powerful testing engine that can be customized with practice exam questions and simulation-based questions, adaptable performance trackers, and the complete text in electronic format.

Which book is right for me?
Self-Study Guides and Exam Certification Guides are intended to complement one another. Though they will cover similar content, they do so in a very different manner. Choosing one book over another depends where you are in the study cycle. If you are familiar with the base concepts, but need to assess your knowledge and review/practice for the exam, we recommend the Exam Certification Guides. If you are new to a topic area and need more detailed discussions of the foundation concepts, we recommend you start with the Self-Study Guides.
