TrySoft is a software development company that focuses on integrated security solutions. The company works to find new clients who need security solutions for their business and develop software to meet their security needs. Along with software development, it provides other services like 24/7 support to customers. The company operates in three different locations: Toronto, Waterloo, and Brampton.

Toronto has three offices in three different buildings, and the distance between the three buildings is not more than 500 meters. Waterloo and Brampton have two offices each, and the distance between different buildings in each city is between 3-4km.

There are four main LAN servers: A database server, a file server, an application server, and a finance server that provides services to all employees in the three locations. These servers are installed in the Main office (Toronto).

Toronto will have 4 subnets: i) Office1 ii) Office2 iii) Office3 iv) LAN Servers

Waterloo and Brampton will have two subnets each: i) Office1 ii) Office2

Now answer the following questions:

Your task is to design a secured hierarchical network that will include all the subnets of Toronto, Waterloo, and Brampton. The design should show Internet Service Providers providing Internet connectivity for all the branches. Draw a 3-layered network diagram for the proposed case study. You must show all three layers: Core, Distribution, and Access. Label the different LANs properly. Your designed network should show how the routers and switches are connected. In your diagram, consider the hierarchy of routers. Feel free to use any number of routers you feel necessary/logical; the design should use the proper symbols for all networking devices.
