CCNP : support study guide (2nd ed)

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 Support exam (640-606) 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.
