Unformatted text preview: Packet Tracer – Network Representation
The network model in this activity incorporates many of the technologies that you will master in your CCNA
studies. It represents a simplified version of how a small to medium-sized business network might look. Feel
free to explore the network on your own. When you are ready, proceed through the following steps and
answer the questions.
Note: It is not important that you understand everything you see and do in this activity. Feel free to explore
the network on your own. If you wish to proceed more systematically, follow the steps below. Answer the
questions to the best of your ability. Step 1: Identify common components of a network as represented in Packet Tracer.
a. The icon toolbar at the bottom left hand corner has various categories of networking components. You
should see categories that correspond to intermediary devices, end devices, and media. The
Connections category (with the lightning bolt icon) represents the networking media supported by Packet © 2015 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public. Page 1 of 4 Packet Tracer – Network Representation
Tracer. There is also an End Devices category and two categories specific to Packet Tracer: Custom
Made Devices and Multiuser Connection.
c. List the intermediary device categories. Routers, Hubs, Switches, Wireless Devices, Security, and WAN
Without entering into the Internet cloud orEmulation.
Intranet cloud, how many icons in the topology represent
endpoint devices (only one connection leading to them)? 14 d. Without counting the two clouds, how many icons in the topology represent intermediary devices (multiple
connections leading to them)? 5 e. How many end devices are not desktop computers? 13 f. How many different types of media connections are used in this network topology? 11 Step 2: Explain the purpose of the devices.
a. In Packet Tracer, only the Server-PT device can act as a server. Desktop or Laptop PCs cannot act as a
server. Based on your studies so far, explain the client-server model. The Client will initiate a request from the server, the server will find the info that the client is searching for
during the queries and will send the response which will either be the data requested or an error. b. List at least two functions of intermediary devices. Regenerate and retransmit signals, Notify other devices of errors and communication failures
c. List at least two criteria for choosing a network media type. distance the media has to travel, the environment Step 3: Compare and contrast LANs and WANs.
a. Explain the difference between a LAN and a WAN. Give examples of each. A LAN is a local area network, something that is typically for a home or small office with very few people
on the network. A WAN or wide area network can have many users at a given amount of time that
connects several WANs which could be used in a large corporation.
b. In the Packet Tracer network, how many WANs do you see? 2
c. How many LANs do you see? 3
d. The Internet in this Packet Tracer network is overly simplified and does not represent the structure and
form of the real Internet. Briefly describe the Internet. The Internet is the largest network on the planet. There are millions of active users on the Internet, it
connects many LANs as well as hosts multiple web servers.
e. What are some of the common ways a home user connects to the Internet? A home user connects to the Internet via a modem, which either has a built in WiFi antenna or they have
a WiFi router that they connect most of their devices on. I prefer an ethernet connection to my devices
that do not need wireless myself.

f. What are some common methods that businesses use to connect to the Internet in your area? A lot of businesses in my area are able to utilize cable or even fiber optic connections in my area. Living
in a metropolitan area makes getting speedy reliable connections easy. Challenge
Now that you have had an opportunity to explore the network represented in this Packet Tracer activity, you
may have picked up a few skills that you would like to try out. Or maybe you would like the opportunity to
explore this network in more detail. Realizing that most of what you see and experience in Packet Tracer is
currently beyond your skill level, here are some challenges you might want to attempt. Do not worry if you
cannot do them all. You will be a Packet Tracer master user and network designer s oon enough. Add an end device to the topology and connect it to one of the LANs with a media connection. What else
does this device need to send data to other end users? Can you provide the information? Is there a way
to verify that you correctly connected the device? Add a new intermediary device to one of the networks and connect it to one of the LANs or WANs with a
media connection. What else does this device need to serve as an intermediary to other devices in the
network? Open a new instance of Packet Tracer. Create a new network with at least two LANs connected by a
WAN. Connect all the devices. Investigate the original Packet Tracer activity to see what else you might
need to do to make your new network functional. Record your thoughts and save your P acket Tracer file.
You may want to revisit your network later after you have mastered a few more skills. © 2015 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public. Page 3 of 4 Packet Tracer – Network Representation Suggested Scoring Rubric
