Hands-On Projects Project 1-1

Steps 1 – 2: After drawing a simple network diagram, students should demonstrate an understanding of the bus topology and peer-to-peer networking concepts. Steps 3 – 4: Students should demonstrate an understanding of the star topology and the path data would follow in a peer-to-peer network using this topology.Steps 5 – 6: Students should become familiar with how nodes are added to a star topology network, then demonstrate how a peer-to-peer network can be transformed into a client/server network. They should also begin to visualize how data travels on a client/server network.Steps 7 – 9: Students should demonstrate how a star-bus topology network is created and begin to visualize how data travels over such a network.

Step 10: Based on students’ experience in sketching some different network types, they should conclude that a network based on a star or star-bus topology is simpler to expand than a bus topology network.Step 11: Students should see that a simple bus topology network requires less cabling and connectivity hardware than the star or star-bus topology networks.

Project 1-2 Steps 1 – 5: Students should become familiar with the steps they’ll commonly use to access networking parameters when adding new network components, modifying network connection and component configurations, and troubleshooting client network problems on a Windows XP workstation.Steps 6 – 11: Students will learn how to share a workstation’s folders over a network, a necessary task when setting up a peer-to-peer network, and a useful task in other networking environments.

Project 1-3 Steps 1 – 5: Students will learn where to check LAN status and settings on a client running the Windows Vista operating system.Steps 6 – 15: Students learn how to enable and configure file sharing in the Windows Vista operating system

Project 1-4 Results from the students’ job searches in this project will vary. However, students should get a sense of which networking skills and specialties are in demand. This project also further familiarizes students who are new to networking with the popular hardware and software products they’ll encounter.

Case Projects

Case Project 1-1 Since Thrift Towne wants an inexpensive solution, does not have many users, and does not care much about security, a peer-to-peer network is an adequate option (though a client/server network would necessarily not be incorrect). In order to make this solution work, the file sharing and access on each computer will need to be modified. If a peer-to-peer solution is recommended, the computer with the most hard disk space should be designated as the central repository for data, though none of the computers on a peer-to-peer network can be considered either a client or a server. If a client/server solution is suggested, that computer should be designated as the server. In addition, each computer ought to be supplied with a Network Interface Card (NIC) and all necessary cabling. This is potentially all the extra software or hardware Thrift Towne would need to purchase in order to implement a peer-to-peer network.

Case Project 1-2The type of network services that can help Scoops determine what type of traffic is crossing their network belong to the network management category of

Network+ Guide to Networks, 5th Edition Solutions 1 – 4

functions. By using various network management tools, Scoops can find out the precise amount of traffic at any time, when the heaviest amount of traffic occurs, and each transmission’s source, destination, and protocol type. After analyzing this data, the IT staff at Scoops can decide if all the traffic is legitimate and necessary. If it is, they can use the traffic volume information to determine whether they need to upgrade their network’s capacity. Given Scoops’ network configuration, it probably also requires file and print services, security services (because of sales and employee data), communications services (for the dial-in capabilities) and Internet services.

Case Project 1-3 Answers will vary, but after researching the differences between Windows Server 2003 and Ubuntu Linux, students should be able to identify the similarities and differences in how the two operating systems handle file sharing, remote access, and mail services. (For example, what software each supports for these services, the ease of configuration, and the type of customer support to expect.) The decision to recommend the use of Linux is also subjective, and might depend on the students’ perception of the ease with which Linux can be managed, compared to Windows Server 2003.
