2. True or False
A repeater typically contains multiple data ports into which the patch cables for network nodes are connected.
If congestion or failures affect the network, a router using dynamic routing can detect the problems and reroute data through a different path.
Hubs operate at the Network layer of the OSI model.
Most bus networks use coaxial cable as their physical medium.
Bus networks are difficult to troubleshoot because it is a challenge to identify fault locations.

4. True or False
A collapsed backbone provides network administrators with the ability to segregate workgroups and, therefore, manage them more easily.
FDDI can connect LANs located in multiple buildings, such as those on college campuses.
A bus topology WAN is often the best option for organizations with only a few sites and the capability to use dedicated circuits.
When computers connect via the PSTN, modems are necessary at both the source and destination because not all of the PSTN is capable of handling digital transmission.
T-Carriers belong to the Network layer of the OSI Model.
