1.XYZ Corp's Nashua, NH, facilities are two office building located 400 feet apart, each with its own LAN. To connect the two networs, you plan to dig a trench and lay cable in conduit between the two buildings. You want to use fiber optic cabl, but you budget-concious facilities manager wants to use thinwire Ethernet. What's the best reason you can use to justify fiber-optic cable in this case?

Answer:

d. Fiber optic leaves more room for growth, and for future needs for increased bandwidth, than thinnet does.

2. TVBCA is moving to the new facilities. Its new campus includes three building, each no more than 100 meters apart from the others. The network is to link all the building together. Each of the building is to be remodeled, so thier plenty of space to run cable and put the network together.

Answer:

a. The propose solution delivered the required result and both of the optional desired result.

3. An advertizing firmdecides to install a network to link all employee's computers together. The campany plans to introduce some video telecomferencing software across the board and plans to use e-mail and database application heavily. Because of the anticipated load on the network, you want it to be as fast as posible.

Answer:

a. The propose solution delivered the required result and both of the optional disered result because the cable is even if expensive but you can recieved many e-mail as fast.

4. XYZ Corp. decides to bring mobile computing to its field engineers. Each field engineer is to be supplied with a laptop, a portable fax/printer, and some kind of wireless transmission device.

Answer:

a. The propose solution deliver the required result and both of the optional desired results because many engeneer can consume and thier work must faster so that they use the GTE MobileNet for $ 2500 a month.

Case project 2

1. Henderson And Associates a mid-size engineering firm, hire 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 server. The company management wants areas to all 40 desks on all floors. The management also want to keep cost down but needs a realable networ. Select a topology or combination of topology to services this company. Draw a map of thier network.



2. The database manager for your company wants to implement a "server farm"(collection of that communicate via high-speed link) for the database server. These servers will be replicated; the network must be operate reliably and quickly yet still be able to connect to other devices (PCs and so forth). Develop two plans, with different topologies, for impleminting this server fsrm; discuse the advantages and disadvantages of each concept.

Answer:

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.

Answer:

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.

Answer:

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.
