The tutorial also discusses various protocols like DNS and DHCP, routing protocols, and securing communications internally and over the Internet. It highlights common network attacks and mitigation strategies, different types of networking equipment, and the use of appropriate cables. Finally, it explores network topologies, including legacy and current designs.
