 CCNA4 Exploration: WAN Technologies |
|
 Course Number |
| CCNA4EXP |
| Course Description |
| This course discusses the WAN technologies and network services required by converged applications in enterprise networks. The course uses the Cisco Network Architecture to introduce integrated network services and explains how to select the appropriate devices and technologies to meet network requirements. Students learn how to implement and configure common data link protocols and how to apply WAN security concepts, principles of traffic, access control, and addressing services. Finally, students learn how to detect, troubleshoot, and correct common enterprise network implementation issues. |
| Performance-Based Objectives |
Students who complete Accessing the WAN will be able to perform the following functions:
- Describe the impact of Voice Over IP and Video Over IP applications on a network
- Identify and correct common network problems at layers 1, 2, 3, and 7 using a layered model approach
- Interpret network diagrams
- Describe the components required for network and Internet communications
- Implement basic switch security measures such as port security, trunk access, and management VLAN’s
- Explain the operation and benefits of DHCP and DNS
- Configure, verify, and troubleshoot DHCP and DNS operations on a router
- Describe current network security threats and explain how to implement a comprehensive security policy to mitigate common threats to network devices, hosts, and applications
- Describe the functions of common security appliances and applications
- Describe recommended security practices to secure network devices
- Describe the purpose and types of access control lists (ACL’s)
- Configure and apply ACL’s based o n network filtering requirements
- Configure and apply an ACL’s to limit Telnet and SSH access to the router using the Security Device Manager command-line interface (SDM/CLI)
- Verify, monitor, and troubleshoot ACL’s in a network environment
- Explain the basic operation of Network Address Translation (N AT)
- Configure N AT forgiven network requirements using SDM/CLI
- Troubleshoot NAT issues
- Describe different methods for connecting to a WAN
- Configure and verify a basic WAN serial connection
- Configure and verify a Point-to-Point Protocol (PPP )connection between Cisco routers
- Configure and verify Frame Relay on Cisco routers
- Troubleshoot WAN implementation issues
- Describe the importance, benefits, role, impact, and components of VPN technology
