Chapter 3 Case Projects

1. 1. D. Fiber-optic leaves more room for growth, and for future needs for increased bandwidth, than thinnet does. Fiber-optic cables are smaller in size and lighter in weight. It can cause lower attenuation than thinnet does.
2. 2. B. The proposed solution delivers the required results and only one of the two optional desired results. It is because fiber-optic cables can support speed 100 mbps and secure as possible from electronic eavesdropping. TVBCA must have sufficient budget for thi type of network.
3. 3. A. Using category 5 UTP cables and hub are common to connect all workstations. Since the network must operate at speed of up to 100 mbps, the proposed solution delivers the required result and both of the optional desired reults because it needs to have a speed of 100 mbps to support the bandwidth of the network to have a fast access as possible.
4. 4. B. The proposed solution delivers the required results and only one of the two optional desired results. It doesn’t emit no external signals that might be detected by any broadcast medium does.
5. 5. C. The proposed solution delivers the required results but neither of the optional desired results. Users on one LAN can communicate with servers on other LAN and vice versa. Thisproposed network solution could not guarantee TVBCA that wireless connection should be secure from electronic eavesdropping because it is very prone to hacking epecially when connection is open or not restricted.
