Demonstrate understanding of wide area network technologies
This standard is about understanding how wide area networks (WANs) work—the technology that connects computers across large distances using the internet. You need to know about the different devices and methods used to build these networks, understand IP addressing and how routers manage traffic, and be able to explain why particular technologies are chosen for different network setups.
You accurately describe what WAN technologies and components are, explain why routers and other devices are used, and show you understand IP addressing and basic protocols.
You compare different WAN technologies and explain the advantages and disadvantages of each; you also clearly explain how TCP/IP layering works and distinguish between static and dynamic IP addressing.
You explain the full picture: how WAN technologies and components work together, how IP addressing schemas are designed, how NAT provides security, and what procedures are needed to manage and monitor WAN links effectively.
