What changes should be made to ensure reliability and resiliency?
A second router running Hot Standby Routing Protocol (HSRP) could be employed at
each dormitory (see Figure 2-9). HSRP automatically detects a network or router failure
and switches to the alternative route. The ZIP students won't miss a click.

What type of cabling topology should be used to provide connectivity?
Cabling recommendations call for fiber-optic cable to be between floors of the dormitory
and in the tunnels across campus. Fiber allows the bandwidth to be scalable while
providing reliable links that are not susceptible to interference. Cat 5 UTP is
recommended for wiring between the workstations and switches.

How can ZIP solve its performance problems?
LAN segmentation is recommended to increase bandwidth.
