You must provide in-text citations and the reference list using Harvard referencing system. Unit Learning Outcomes: Learning Outcomes By the end of this unit students will be able to: LO1: Explore LAN design principles and their application in the network design process. LO2: Implement a network using LAN design principles based on a predefined set of requirements. LO3: Produce an appropriate WAN solution to a set of organisational requirements. LO4: Solve a range of network related problems using appropriate troubleshooting techniques and methods. 10

Assignment Brief and Guidance: 11

  • Sales and Marketing Team should be able to access resources at Kandy office and the head office securely during the field visits.
  • Proper methods for networking monitoring and troubleshooting need to be established.
  • Customer Care and Sales team should not be allowed to access the Finance Web server in Kandy server Room.
  • All possible network security mechanisms should be implemented. Assume you are a trainee network engineer at EMC Solutions. Prepare a network architectural design and implementation 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) Task 1 1.1. What do you mean by Network Design Model? Examine the Network Design 13

Models and their features. Justify your suggestion for the above scenario. 1.2. Discuss and analyze LAN redundancy, bandwidth and load related issues with reference to Layer 2/ Layer 3 redundancy protocols , and discuss possible solutions that could be provided for the above scenario. 1.3. Evaluate different Link Aggregation protocols used in the industry. Recommend a protocol/protocols for the above scenario and justify your selection. Task 2 2.1. Select LAN devices based on features and requirements. 2.2. Provide IP allocation plan and design the network for EMC Solutions (including WAN) applying basic configuration commands for the network connectivity in the LAN. 2.3. Implement Layer 2 and Layer 3 redundancy using switch and router redundancy protocols in your network. Analyse the redundancy implementations for IPv4 and IPv6. *Note: - Screenshots of Configuration scripts should be presented. Task 3 3.1. Examine various WAN technologies for the given scenario and analyse the benefits and drawbacks of them. Select the appropriate WAN technology for EMC solutions. 3.2. Configure appropriate WAN protocols for the above scenario. 3.3. Evaluate features and benefits of different VPN types that could be used for the above scenario. *Note: - Screenshots of Configuration scripts should be presented. Task 4 4.1. Explain the importance of Network monitoring and troubleshooting to establish network baselines and produce network documentation. Deploy the same. 14
