In this chapter, we learned the nuances of creating a network topology in Packet Tracer, the types of connections available, and link statuses. We also saw how to test connectivity by using simple and complex PDUs. The test feature will help you a lot as you build complex topologies. Then we saw the simulation mode of Packet Tracer—go ahead and explore this mode using hubs and look at the difference between hubs and switches. Finally, we learned about creating and managing clusters.

In the next chapter, we will move the physical workspace of Packet Tracer and start creating wiring closets, offices, and entire cities! You will learn about the physical limitations of each network technology and the purpose of devices such as repeaters.
