CCNA Certification Kit

Cisco Systems continues to dominate the internetworking hardware market with a more than 80 percent share of the routers used on the Internet. The Cisco Certified Network Associate (CCNA) certification is the first-tier certification in Cisco's Network Support and Communications & Services tracks and by far its most popular. Cisco recently refreshed the CCNA exam, assigning it a new exam number, 640-607, and expanding the question pool. In addition to standard multiple-choice questions, they've now added simulation and drag-and-drop format questions. The objectives, however, remain the same.
