CCNA 4: Accessing the WAN

@ Honolulu Community College


Accessing the WAN explains the principles of traffic control and access control lists (ACLs) and provides an overview of the services and protocols at the data link layer for wide-area access. You will learn about user access technologies and devices and discover how to implement and configure Point-to-Point Protocol (PPP), Point-to-Point Protocol over Ethernet (PPPoE), DSL, and Frame Relay. WAN security concepts, tunneling, and VPN basics are introduced. The course concludes with a discussion of the special network services required by converged applications and an introduction to quality of service (QoS). With Cisco Academy courses, you experience the benefit of online curriculum from Cisco reinforced through hands-on labs. CCNA 4 Exploration: Accessing the WAN is the fourth of four courses leading to the Cisco Certified Network Associate (CCNA) designation.
