Concept Questions 1. A WAN is used to interconnect local-area networks (LANs) that are typically separated by a large geographic area. A WAN operates at the OSI reference model physical and data link layers. The WAN provides for the exchange of data packets/frames between routers/bridges and the LANs that they support. Draw a WAN that includes three LANs. 1 of 116 CCNA 2 Chapter 1 WANs and Routers 2. Compare and contrast WANs and LANs layer by layer. 3. Routers and the modern PC have many hardware

Chapter 4 Review Questions 1. A network-layer packet is a datagram. A router forwards a packet based on the packet’s IP (layer 3) address. A link-layer switch forwards a packet based on the packet’s MAC (layer 2) address. 2. Datagram-based network layer: forwarding; routing. Additional function of VCbased network layer: call setup. 3. Forwarding is about moving a packet from a router’s input link to the appropriate output link. Routing is about determining the end-to-routes between sources and destinations

address is used mostly for identifying and sending information to hosts that are on the same network, or Ethernet. If you need to connect to a device on a network outside of your home or business network, however, you will need the logical address (or TCP/IP address). The example that was given in a book excerpt on informit.com was extremely helpful for me to understand the concept of network addressing. In Barry Press’ book, “Networking by Example”, he uses the example of finding a specific house
