Exercise 4.1: Matching Topologies to Applications
Objective: Practice associating network topologies with appropriate uses.

Time estimate: 10 minutes.

Match the topology to the application. For this exercise, you should be familiar with the material in this chapter and also in Chapter 3.
  1. 10BASE2
  2. 10BASE5
  3. 10BASE-T
  4. 10BASE-FL
5. 100BASE-X

6. Token Ring
A.You are looking for an inexpensive network with the maximum flexibility for future expansion. You want to utilize existing data-grade phone lines for some segments.
  1. Your network encompasses three buildings. The longest segment length is 450 meters. You want to minimize cost. Differences in electrical ground potential between the buildings is not a problem.
C.Your company encompasses three buildings. The longest segment length is 1,800 meters. In previous networking attempts, you have experienced problems with the ground potential differences between the buildings.
D.You are designing a network for an airline ticket office. Employees query the database constantly, so the network utilization rate is extremely high. The network must be very reliable and capable of self-corrective action to isolate a malfunctioning PC.
E.You work in a small office with 12 PCs. You are looking for an inexpensive networking solution. The computers are spaced evenly throughout the office (approximately 3-5 meters between workstations). You want to minimize the total amount of cabling.
F.Your company colorizes Hollywood movies. Huge, digitized movie files, such as Bringing Up Baby or The Jazz Singer, must pass quickly through the network so they will arrive with extreme dispatch at colorizing workstations. Very high transmission speeds are required. Your company is reaping huge profits, so the cost of cabling is no concern.

The correct responses are as follows:
 
1.E
2.B
3.A
4.C
5.F
