You have successfully installed Packet Tracer and used it to create a simple topology. Keep trying different topologies with only PCs/laptops and switches to familiarize yourself with the GUI. You have also seen a list of protocols supported by Packet Tracer; use this list as a reference. Whenever you want to try a new technology in the future, make sure that the protocols to be configured are fully supported by Packet Tracer before moving ahead.

In the next chapter, you'll learn about the different types of network devices and how to customize them according to your needs. You'll also see how to configure them through the CLI as well as through the graphical interface.
