Cisco ICND1 1.1: WAN Technologies

This course is included in our On-demand training solution.


When sites are located at different geographic locations, a WAN provides interconnections between the sites. There are several types of WANs, including point-to-point leased lines, circuit-switched networks, and packet-switched networks, which are discussed in this course. Routing is the process by which information gets from one location to another. It is important to understand how the various routing protocols determine IP routes. This course describes the features and operation of static routing, default routing, and Routing Information Protocol. As organizations merge, addresses sometimes become limited or addressing conflicts arise. Network Address Translation (NAT) and Port Address Translation (PAT) are two protocols that you can use to address these issues and these protocols are also described in this course.

Target Audience

Network administrators, network engineers, network managers, network designers, and project managers; individuals seeking the Cisco Certified Entry Network Technician (CCNET) certification and those individuals targeting the Cisco Certified Network Associate (CCNA) certification
