Henderson & Associates, a mid-sized engineering firm, hired you as a consultant to design their network. The company occupies three floors in a building downtown with PCs on all 40 desks and three servers. The company management wants access to all 40 desks on all floors. The management also wants to keep costs down but needs a reliable network. Select a topology or combination of topologies to service this company. Draw a map of this network.
Supposing that these are all the 40 PCs and 1 on the company manager and the three servers.

2.The database manager for your company wants to implement a “server farm” (a collection of servers that communicate via a high-speed link) for the database servers. These servers will be replicated; the network must operate reliability and quickly yet still be able to connect to other devices (PCs and so forth). Develop two plans, with different topologies, for implementing this server farm; discuss the advantages and disadvantages of each concept.
Star topology, host are connected to each other through a central controller which assumes all responsibility for routing messages to the appropriate hest. Data flow between the hosts and the central controller is represented by dotted lines. Direct host-to-host communication isn’t permitted. Ring topology, hosts are connected to each other in a circular fashion with data flowing in one direction only. The network can be connected to other networks via a bridge or gateway. If the other network has the same protocol, a bridge is used to connect the networks. If the other network has different protocol, a gateway is used.
3. Design networks for two classroom environment – a permanent facility and a traveling classroom. They must have connectivity for 20 PCs and a server, and be inexpensive and easy to set up. Present both versions of this design to the class and discuss the benefits of each.
A hybrid topology with a version of two networks that combines a star and a ring, connected by a bridge. The star topology can be used to a permanent classroom which has a central controller that one of its connection can be connected to the bridge that is also connected to the ring topology and this ring topology can be use to the traveling classroom.
4. Design a network for 3 – D imaging firm. It must have connectivity for 40 high-speed imaging workstations and two servers. This network must support high performance and easy reconfiguration into as many as eight workgroups, any of which may have as many as a dozen members. Explain the kind of networking device required to create such an environment and why it’s the only choice for this particular kind of networking implementation.
Switched network is required to create such an environment. It can impose whatever kind of topology it likes on the groups of devices that make up the VLANs that the switch recognizes and controls, as well as the interconnections among whatever VLANs exist in that switch’s configuration.
