Answer to Question 1

TRUE

Answer to Question 2

A collapsed backbone connects all of the network segments to a central, single router or switch. This central device is, in effect, the backbone. The network segments typically connect to the central backbone device by means of a hub, switch, or router. Because only a single, central backbone device is used, cabling is greatly reduced. Furthermore, additional connecting devices are not required. A collapsed backbone can result in significant cost savings. Also, because the collapsed backbone is a device and does not use a central cable, as does a distributed backbone, a separate protocol for the backbone is not required. This means, for example, that a collection of Fast Ethernet network segments could connect to a Fast Ethernet-based switch or router. A collapsed backbone's central connecting router or switch makes use of something called a backplane.
