1 CHAPTER 15 Connecting LANs, Backbone Networks, and Virtual Networks Solutions to Review Questions and Exercises Review Questions 1. An amplifier amplifies the signal, as well as noise that may come with the signal, whereas a repeater regenerates the signal, bit for bit, at the original strength. 2. Bridges have access to station physical addresses and can forward a packet to the appropriate segment of the network. In this way, they filter traffic and help control congestion. 3. A transparent bridge is a bridge in which the stations are completely unaware of the bridge’s existence. If a bridge is added or deleted from the system, reconfigura- tion of the stations is unnecessary. 4. A signal can only travel so far before it becomes corrupted. A repeater regenerates the original signal; the signal can continue to travel and the LAN length is thus extended. 5. A hub is a multiport repeater . 6. A forwarding port forwards a frame that it receives; a blocking port does not. 7. In a bus backbone , the topology of the backbone is a bus ; in a star backbone , the topology is a star . 8. A VLAN saves time and money because reconfiguration is done through software.
