Cisco dominates the internetworking scene with an over 80 percent share of the routers used on the internet. The mid-level cisco certified network professional (ccnp) certification validates advanced knowledge of cisco-based networks. The remote access exam (640-605) is one of the four core exams 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.
