Question

Due to an upswing in the economy, the volume of production and sales of these products dramatically increased. This increase in volume has finally forced Nigercem Inc. and Nwakuba Sales Company to computerize their record keeping and data communication. Both companies are willing to buy desk top workstations for each employee, a printer for each department, and departmental servers for data storage and processing. In addition, there will be an enterprise you server for each company. Some applications require exchange between departments, though you should keep local data traffic local. Each employee should also have access to electronic mail messages. Nigercem Inc. has applied to an ISP Provider, and has been given a network address: 201.10.10.0 TASK: You have been awarded the contract (as a Network Consultant), to design a network system for both companies. Since both companies and departments exchange data, design and draw a viable, cost effective and secured network system for Nigercem Inc. and Nwakuba Sales Company that will: Show how Nigercem Inc. Network is connected to Nwakuba Sales Company Network (Companies that are fifty miles apart). What security measures are in place to protect both networks unauthorized access to internal LAN, web server, and email server? Allow each company to process and store their enterprise-wide data in an enterprise Server. Allow each department in their respective companies to process and store their departmental server, and print from their departmental printers. Identify all interconnecting devices and media used (name and speed). What is the Subnet Mask (not default) of Nigercem Inc. Network System How many possible subnets can be created in Nigercem Network system?

Explanation / Answer

1. Since both companies are 50 miles apart WAN ( wide area network) is the way to get connected.

a) Contains multiple LAN's for interconnecting within the area.

2.Security measures:

a. Common security measure is having a firewall. The firewall protects everything "behind" it from everything in "front" of it.

b.Virus protection: Antivirus systems,security patches

c.Intrusion-detection systems

d.Port scanners , Network sniffers

e.Emails: Malware , Spam and phishing

3.SAN solution for Data storage

4. For printing it's LAN ( local area network) connected to local printer and firewall server.

5. Interconnecting devices

a. computer , laptops , printers,

b.CATs wires , WIFI routers , Network routers

c.Firewall , DNS server , EMAIL server, WebServer ( machines) ,

d. Storage Server and it's connecting equipments, Disk , FC ( fiber channels)

6. subnet Mask:

An IP address has two components, the network address and the host address. A subnet mask separates the IP address into the network and host addresses (<network><host>). Subnetting further divides the host part of an IP address into a subnet and host address (<network><subnet><host>) if additional subnetwork is needed.

there are 4 different types Networks and typicall they are catogerised based on geographic location In order to further divide within each geogrphy it's again subdived by subnetting. done by subnet mask .

Netmasks for classed networks are 8-bits (Class A), 16-bits (Class B) and 24-bits (Class C), and classless networks

7. No of subnets:

It would depend on subnet masking and maximum upto 256 subnets 2^8 ( last eight bits can be masked)
