Question

You are the IT manager of Schaumburg Elementary School. The school is adding computers that have been donated by a local company. An extended star topology has been suggested, using some hubs that are available. The school agrees with your idea of adding a switch working as a backbone switch. The plan is to replace the classroom hubs as the budget allows.

Scenario: For now, the very basic details are as follows: Schaumburg elementary is a four-year-old, single-level building with 12 classrooms and a library. Each classroom currently has 24 students but could possibly seat 32 students. There are currently no portable classrooms but a student enrollment growth is just starting to hit the school.

Enough computer are available for 6 classrooms and the library immediately, and the intent is to outfit the remaining 6 classrooms next year. The plan is to make the internet and some online services available to students. The computers are current enough to be useful for at least 2 years.

The library, which is somewhat centrally located, is where the server(s) and router connecting the school to the internet will be located. Assume that all rooms will have 24 computers and that each room will use stackable switch solution that combines a 12-port switch and a 24-port switch for 36 total ports. Being stackable units, the network will see each stack as a single 36-port device.

1. Review the above room requirements to conclude what type of network media is most appropriate for this situation?
2. How many IP addresses does the school need immediately? How many might it eventually need for initial seven rooms? How many could it need if it gets enough computers for the entire school? Exact numbers aren't expected' but estimate pretty close.
3. What class(es) of IP address do you need now and in the future?
4. The school district informs the group that it can afford 2 public IP addresses for the internet access. Is this a problem if the school wants all the computers to access the Internet? Explain why or why not.
5. Look up links to find prices of routers, cable, and switches.

Explanation / Answer

1.      A fibre optical cable can be used as a network medium because it is more secure and can connect systems over large distances.

2.      The school may immediately need 145 IP addresses. Since it needs to provide access to 6 class rooms and library, it needs a minimum of 145 IP addresses. As there will be 24 computers in each class (24 x 6 =144) and 1 server system for the library room.

3. Class C addresses can serve the purpose. A class C address range can accommodate 254 hosts per network. Since the school needs to accommodate 145 hosts at present and another 6 class rooms (144 hosts) later, class C address range is suited.
