Network Assignments

  1. Create a tiny text document with WordPad. Save it as a Text file, an RTF file, and a Unicode file. Use debug to display the raw data for all three files. Describe the results. Use the Control Panel/Regional and Language Options to install a different language set. Use the keyboard (Alt-left Shift) and enter characters from the new language. Save the Unicode file and use debug to compare it to the original file.
    Perform the following computations by converting the data to binary values. Test your answers using the Windows calculator.
    89 AND 63
    89 AND 64
    123 AND 571
    123 OR 571
    5763 AND 127
  2. Summarize the main types of fiber optic cable, and identify their strengths and weaknesses. If you want to install new fiber between two building on campus, what would you recommend and why?
  3. Teamwork assignment. Set up all of the local PCs for our network lab. Build connection cables if necessary. Install the Windows software. Assign all of them to a single workgroup and define user accounts. Configure the client computers so that one folder on each machine can contain files that are accessible to the other machines in the workgroup.
  4. Teamwork assignment. Use Ethereal to capture your network traffic for a few minutes of time. You might want to connect the client computer to the campus network/Internet and try sending e-mail or some other task. Include a small piece of the captured data and briefly describe what was captured. Identify the various elements of the captured segment and their role in the network.
  5. The university has a Class B Internet address (138.9). Count the number of buildings on campus. If the university wants to create a subnet for each building, what subnet mask would be needed? Using Internet or other resources, identify the maximum number of hosts/client computers supported within each subnet. Briefly comment on your findings and identify possible problems.
  6. Teamwork assignment (one team for each server). A continuation of Lab 6. Finish the server and client configurations. Demonstrate the network and briefly describe any problems you encountered.
  7. Configure FTP and IIS on your server. Create simple HTML files to test the server. Use FTP to transfer a small file. Monitor the transfer with Ethereal and comment on the results.
  8. Teamwork assignment. Continue the Active Directory installation. Add the client computer to the AD.
  9. Choose a country (not the U.S. or Canada). Assuming you work for a company that wants to install a high-speed network connection in that country, identify how you would obtain that service and who could provide it. If possible, estimate how long it would take to get installed and the approximate costs.
  10. Assume your organization has three subnets: Administration: 115.90.10.xxx, Marketing: 115.90.20.xxx, and Manufacturing: 115.90.30.xxx. You need to configure the Administration router so that Marketing has no access to the Administration subnet, except for the marketing director’s computer (115.90.20.9). Everyone in the manufacturing subnet has access to the Administration subnet. Write the Cisco router access list commands to provide these conditions. Now, add an extended access list command so that anyone in the marketing group has access to the administrative Web site (TCP port 80).
  11. NEVER do this on a real network, including the university network! Download a port scanner and install it on one of the client computers of the class network. Run the scanner against a server and another client. Turn off the firewall for one of the clients and run the scanner against that client. Briefly summarize the results.
  12. Research the current status of IPv6. Find specific hardware, including network cards and routers that will support native IPv6. What is the Microsoft policy on transitioning to IPv6?
