You have been approached by Company XYZ to design and deploy new branch offices to their network that will span three cities in Queensland: Brisbane (1300 users) Gold Coast (400 users) Cairns (200 users) The company uses 180.67.0.0/16 at the company headquarters in Sydney with 3500 users and need to use a subnetting structure to incorporate the new cities. Adhering to the subnetting scheme and using VLSM, assign a subnet address to the networks and their links. Access to the Internet is crucial for each office, as well as inter-branch-office networking. The large companys headquarters is in NSW and the new subnets must have connectivity. For the QLD operation, you can choose any routing protocol, but you need to explain the reason for your choice. The communication for each Branch should be encrypted and cost-effective. The main office network has been compromised with a DOS attack. What should you do to protect networks company against these types of attacks in future? Elements: Your goal is to design, deploy and successfully implement their business requirements using all of the following: Switches Routers Workstations IP addressing hosts, subnet addresses, broadcast addresses Default routes Cables Solution: You are required to design the topology for the three new sub-networks and their connection to the Sydney office. You must document each step you have taken, including your research sources. You need to come with design report and send it to your technical manager. Report: The report must contain the following sections: Introduction: Critical analysis of networking requirements Local Area Network (LAN): Design and description of Local Area Network for all subnets which must include: Network topology: Discuss the reasons for choosing the particular network topology. LAN design connections to the servers, connection to other subnets, and also the internet/intranet Hardware: Provide a complete description of all interconnecting devices (switches, routers, hubs, and access points) and wiring used to build the network. Provide justification for your choice. Conclusion: Comprehensive summary of the work done and recommendations, I just wanted the answer of this You are required to design the topology for the three new sub-networks and their connection to the Sydney office. You must document each step you have taken, including your research sources.
