Features: This study guide for the revised CCNP exam: 642-831 provides readers with: in-depth explanations of key exam content; practical information on troubleshooting and optimizing Cisco networks; hundreds of challenging review questions; and an optional CD-ROM featuring new exam review software, including test engine, sample simulation questions, and electronic flashcards. As the true uncrowned king in the field of routing and switching, Cisco has established a series of certification exams to ensure that technicians using, managing, or providing Cisco product services possess the corresponding technical expertise, with their exam objectives and content constantly evolving along with their products. To cover the new exam objectives, we adopt the approach of "original import, reprinted and reorganized" to quickly publish a series of study guides for Cisco certification exams that meet reader demand. This book, as one in the series, is designed for the CCNP: 642-831 exam. The content begins with a methodology for troubleshooting, first introducing configuration tables and topology diagrams, the OSI reference model, and connection-oriented and connectionless protocols. It then covers the use of Cisco built-in diagnostic tools, serial connections, and Frame Relay connections, followed by ISDN and related protocols, and the Catalyst series switches. The book concludes with a real-world example that integrates the knowledge from the entire book. Each chapter includes numerous review questions and answers, with content that is appropriately sized and fresh and practical, making it suitable not only for network administrators, network designers, and developers but also as essential material for CCNP candidates.
