Complete a network diagram for the entire building
Answer the following questions
1) Your friend just purchased a 3 story building in downtown. He plans to sublet the building to local businesses/entrepreneurs with the goal of subdividing each floor to 4 separate businesses/spaces. Century Link assigned the IP address of 200.100.21.0 to your friend. Your friend is asking you to:
a) Complete a network diagram for the entire building. You must use Microsoft Visio to design your network. You must use CISCO 3 tier Architecture as the basis of your network design. You must use subnetting to provide security for each business.
b) For each subnet in your network design; Identify all subnets by its Subnet ID/IP along with its subnet mask, CIDR, usable IP addresses for all nodes in the subnet and the subnet broadcast IP addresses. Use a separate pdf sheet for this.
