Cisco's 640-802 Cisco Certified Network Associate (CCNA) is the composite exam associated with the Cisco Certified Network Associate certification.

Cisco has specified over seventy-five objectives for the 640-802 exam to test a candidate's knowledge and skills required to successfully install, operate, and troubleshoot a small to medium size enterprise branch network. The topics include connecting to a WAN; implementing network security; network types; network media; routing and switching fundamentals; the TCP/IP and OSI models; IP addressing; WAN technologies; operating and configuring IOS devices; extending switched networks with VLANs; determining IP routes; managing IP traffic with access lists; establishing point-to-point connections; and establishing Frame Relay connections.

Following are some important areas in which a candidate should possess good knowledge before taking the 640-802 exam:

1. Purpose and functions of various network devices.


2. Components required to meet a given network specification.


3. OSI and TCP/IP models and their associated protocols to explain how data flows in a network.


4. Common networking applications including Web applications.


5. Interpreting network diagrams.


6. Determining the path between two hosts across a network.


7. Identifying and correcting common network problems at layers 1, 2, 3, and 7 using a layered model approach.


8. Selecting the appropriate media, cables, ports, and connectors to connect switches/routers to other network devices and hosts.


9. The technology and media access control method for Ethernet technologies.


10. Network segmentation and basic traffic management concepts.


11. The operation of Cisco switches and basic switching concepts.


12. Remote access management.


13. Verifying network status and switch operation using basic utilities (including ping, traceroute, telnet, SSH, arp, ipconfig), SHOW and DEBUG commands.


14. The basic uses and operation of NAT in a small network connecting to one ISP.


15. Identifying and correcting IP addressing issues.


16. Basic routing concepts.


17. The operation of Cisco routers.


18. Accessing and utilizing the router CLI to set basic parameters.


19. The basic parameters to configure on a wireless network.


20. The functions of common security appliances and applications.


21. Configuring, verifying, and troubleshooting VLANs and trunking on Cisco switches.


22. Configuring, verifying, and troubleshooting VTP, interVLAN routing, and RSTP operation.


23. Interpreting the output of various show and debug commands for verifying the operational status of a Cisco switched network.


24. Implementing basic switch security including port security, unassigned ports, trunk access, etc.


25. Calculating and applying a VLSM IP addressing design to a network.


26. Determining the appropriate classless addressing scheme using VLSM and summarization to satisfy addressing requirements in a LAN/WAN environment.


27. Describing the IPv6 addressing and technological requirements for running IPv6.


28. Identifying and correcting common problems associated with IP addressing and host configurations.


29. Comparing and contrasting methods of routing and routing protocols.


30. Configure, verify and troubleshoot OSPF and EIGRP.


31. Verifying configuration and connectivity using ping, traceroute, and telnet or SSH.


32. Troubleshooting routing implementation issues and implementing basic router security.


33. Verifying router hardware and software operation using SHOW and DEBUG commands.


34. Describing, configuring, and applying access control lists.


35. Troubleshooting ACL implementation issues and verifying and monitoring ACL's in a network environment.


36. Explaining, troubleshooting, and configuring NAT for given network requirements using Command-line interface (CLI).


37. Configuring and verifying Frame Relay on Cisco routers.


38. Troubleshooting WAN implementation issues.


39. Describing VPN technology including importance, benefits, role, impact, and components.


40. Configuring and verifying PPP connection between Cisco routers.
