ICND2 2.0: Wan Technology Overview and Serial Connections

Anyone wishing to obtain Cisco Certified Network Associate (CCNA) 200-120 certification that validates the knowledge and skills required to install, operate, and troubleshoot a medium-sized network, including connecting to a WAN and implementing network security. Interconnecting Cisco Network Devices Part 2 (200-101 ICND2) is an essential course for students preparing for the CCNA Routing and Switching certification or the ICND2 certification. Students pursuing the CCNA Routing and Switching certification should attend parts 1 & 2 of the ICND course.Network administrators, network engineers, network managers, network designers, and project managers. Familiarity with network fundamentals, implementing local area networks, Internet connectivity, managing network device security, implementing WAN connectivity and basic IPv6 connectivity is recommended.

Description
As an enterprise grows beyond a single location, it needs to interconnect LANs in various locations using a WAN. There are several technologies that are involved in the functioning of WANs, including hardware devices and software functions. This course describes the functions and characteristics of WANs and contrasts them with LANs. The course also explores how WANs relate to the OSI reference model in their design and function and which major hardware components are typically used in WAN environments.
One of the most common types of WAN connection is the point-to-point connection. Point-to-point connections are used to connect LANs to service provider WANs and to connect LAN segments within an enterprise network. A LAN-to-WAN, point-to-point connection is also referred to as a serial connection or leased-line connection. WAN services are typically leased from a service provider. Some WAN services operate as Layer 2 connections between your remote locations and are typically provided by a telco provider over its WAN switches.
PPP emerged as an encapsulation protocol for transporting IP traffic over point-to-point (leased line) serial connections. PPP encapsulation has been carefully designed to retain compatibility with most commonly used supporting hardware. This course highlights the operation, configuration, and verification of PPP.
