CCNP BSCI Exam Certification Guide (CCNP Self-Study) is a revised edition of the all-time best-selling CCNP BSCI/CCNP Routing title ever! With updated technology and testing content, this book provides exceptional tutorial learning and exam preparation on advanced routing techniques and practices. It matches all the objectives of the new 642-801 BSCI exam launched in April! Written in smaller, easier to absorb chapters, this book breaks down larger concepts into manageable blocks of learning. This, combined with other new learning elements and a complete re-writing of the material, make it even easier to comprehend and retain the large amount of learning required for this essential building block of learning for a networker. As part of the CCNP, CCDP, and CCIP certifications, routing is an important building block that all networking professionals must master. This book teaches and prepares candidates for this challenging professional-level exam with chapter quizzes, foundation reviews, in-depth topical learning materials, real-world case studies, and, of course, the 200-plus question electronic testing engine on the CD-ROM included in the back of the book. This testing engine even includes simulation-based questions, just like on the actual exam. New coverage includes more on IS-IS (Intermediate System to Intermediate System), NAT (Network Address Translation), and a solid introduction to IPv6.
