Appendix B. DCICN Exam Updates

Over time, reader feedback allows Cisco Press to gauge which topics give our readers the most problems when taking the exams. Additionally, Cisco might make small changes in the breadth of exam topics or in the emphasis of certain topics. To assist readers with those topics, the authors create new materials clarifying and expanding upon those troublesome exam topics.

DCICN has been updated with a few new topics. Therefore, we have updated in this book to cover those new exam topics. We have added chapters on the following topics to cover the changes in the exam topics provided by Cisco:

Chapter 1: Introduction to Nexus Data Center Infrastructure and Architecture

Chapter 20: Nexus First-Hop Redundancy Protocols and Configurations

Part V: Data Center Storage Technologies

Chapter 22: Introduction to Storage and Storage Networking

Chapter 23: Advanced Data Center Storage
