Packet Tracer - WAN ConceptsObjectivesIn this activity, you will investigate various types of WANs by exploring a topology that uses diverse connectivity technologies.Describe different WAN connectivity options.Background / ScenarioYou will explore WAN technologies that are used to connect business and home users to data services.Note:There is no scoring in this activity.InstructionsPart 1: Investigate Consumer WAN Technologies for Home and Mobile Devices.Step 1: Explore Consumer WAN Technologies.In this step, you will explore three consumer WAN technologies and home networks.a.Look at the two home networks.Question:What are the WAN technologies in use?The home networks use cable and DSL WAN technologies.Type your answers here.b.Examine the connections used in the network topology by selecting the Connections icon (the orange lightning bolt) in the PT devices menu. Hover over the media icons to display their names in the white boxat the bottom of the PT window.Question:What media is used to connect the two home networks to the ISP? What devices in the home networks are directly connected to the ISP?The cable network uses coaxial cable to link the Home Cable Network to the ISP, with the coaxial cable connecting to a splitter device. The DSL network is connected to the ISP via phone cable, which connectsto the DSL modem.Type your answers here.c.Click the DSL modem and open the Physical tab.Questions:What ports are available on the device and what is connected to them?The DSL modem has two ports: one connects to the phone line from the Telco, while the other connects to the home LAN through Ethernet.Type your answers here.2019 - 2019 Cisco and/or its affiliates.

Packet Tracer - WAN ConceptsWhat is the purpose of the DSL modem?It converts the telephone data network signals to Ethernet for the home network.Type your answers here.What is the type of connection between the ISP/Telco/Cable Company network and the Home Cable Network? Why is the splitter necessary?The home connection is made using coaxial cable. A splitter is required because the cable carries both digital data and video signals. The splitter separates the signals, directing the data to the cable modem and the video to the TV.Type your answers here.d.Look at the ports on the cable modem.Questions:What does the cable modem do? What connections does it have?The cable modem converts the cable data signals into Ethernet signals. It is connected to the coaxial cable from the splitter and the UTP cable from the Ethernet interface.Type your answers here.Which port does the cable from the cable modem connect to on the home wireless router? Where did the interface IP address come from?It connects to the internet interface. The IP address came from the ISP network over DHCP.Type your answers here.e.Look at the Smartphone.Question:What is its IP address? Where did the IP address come from?The IP address is 198.51.100.100, and it must have been assigned by the Telco network via DHCP.Type your answers here.What data service is the cellphone currently using (cellular data or Wi-Fi)?The phone is currently using cellular data from the 3G/4G network.Type your answers here.Step 2: Explore the Business WANIn this step you will explore the business WAN. The business is a retail tire store. It has a local headquarters where most of the business functions occur, and three stores that are connected to the business WAN.a.Look at the Connections menu.Question:What different types of connections do you see in use in the Business network?Ethernet over copper and fiber and also serial.Type your answers here.b.Open the physical view for the StoreNet switch.Question:What types of interfaces are present? You may need to zoom and scroll the view to see.2019 - 2019 Cisco and/or its affiliates. All rights reserved. Cisco PublicPage 2of 3www.netacad.com
Packet Tracer - WAN ConceptsThe switch features Gigabit Ethernet copper media ports and four modular ports. Three GLC-LH-SMD fiber optic Small Form-Factor Pluggable (SFP) modules are installed in the modular ports, allowing the switch to connect to fiber optic Ethernet networks.Type your answers here.Which interfaces and media are used to connect the store networks to the Business Headquarters network? Why was this done?The stores are connected to the StoreNet switch via Ethernet over fiber optic cables due to the distance needed to reach the stores. In a real-world scenario, a different provider would supply the fiber optic service, but this has been simplified for the purposes of this activity.Type your answers here.What type of WAN service is used to connect the Business Headquarters router to the ISP?The router uses a serial WAN connection to connect to the ISP.Type your answers here.Part 2: Explore ConnectivityQuestions:Ping devices within the Business WAN and the Consumer WAN networks. Also ping between the networks and the between the networks and the web server. Can all hosts ping each other and the web server?Hosts in both networks can ping the webserver, but hosts on the Business WAN network cannot ping hosts on the Consumer WAN network, and vice versa.Type your answers here.Is this a good situation?Yes, these networks should be inaccessible from the outside for security reasons.Type your answers here.End of document2019 - 2019 Cisco and/or its affiliates.
