Scenario:

Case Study:

Fushia Group is a privately owned, well-known Software company located in Colombo. The Management of Fushia Group has purchased a 3-story building in the heart of Kandy. They are planning to make it one of the state-of-the-art companies in Kandy with the latest facilities. It is expected to have nearly 350 employees in Kandy branch.

Following requirements are given by the Management.
• All the departments must be separated with unique subnet and should not communicate with each other unless there is a special requirement.
• 192.168.10.0/24 is given and should be used for all the departments except the server room. IPs should assign using DHCP.
• ERP and CRM Systems need to be implemented in Kandy branch in local servers.
• Number of servers required for the Server room need to be decided by the Network designer and should be assigned with 10.254.1.0/24 subnet. (Uses static IPs)
• High level of redundancy is expected in network design to eliminate single point of failures and traffic bottle necks.
• Sales and Marketing Team need to access Network resources using WIFI connectivity.
• Proper methods for networking monitoring and troubleshooting need to be established.
• All possible network security mechanisms should be implemented.

Assume you have been appointed as the new network consultant of Fushia Group. Prepare a network architectural design and implement it with your suggestions and recommendations to meet the company requirements.

(Note: Clearly state your assumptions. You are allowed to design the network according to your assumptions, but main requirements should not be violated)

5. Design a detailed Maintenance schedule for above Network design.

Task 04
1. Implement and configure all network devices* according to the requirements given in the scenario.
2. Conduct verification with e.g., Ping, extended ping, trace route, telnet, SSH, etc.
3. Provide troubleshooting steps for following situations.
1. Everything is working normally but suddenly the connection goes away, and then comes back, and then goes away again on client computer. (i.e., flapping)
2. Network cable plugged in but getting no connection.
4. Recommend potential future enhancements for the networked system and justify your recommendations.
5. Write a conclusion for your report by Critically evaluating design, planning, Configuration and testing of your network.
