Cisco dominates the internetworking market with more than 80% share of the routers used on the Internet. The mid-level Cisco Certified Network Professional (CCNP) certification validates advanced knowledge of Cisco-based networks. Candidates must pass four exams -- Routing, Switching, Remote Access, and Support -- that cover a wide range of topics, including installing, configuring, and operating LAN, WAN, and dial-up access services for organizations with mid-to-large sized networks. Cisco recently "refreshed" the four CCNP exams, adding new questions and question formats to the pool. The exam objectives have not changed.
