The book focuses on the new CCNP 642-831 CIT exam and helps improve both your conceptual and hands-on knowledge. Among other things, it discusses methods of troubleshooting, working on OSI models from the physical to application layer. The accompanying CD has multiple-choice questions. Each chapter in this book starts with a quiz which lets you decide whether you need to read that chapter throughout or not.
