Domain 2 of the Network Plus exam shifts focus from theory to real-world implementation—how devices are configured, deployed, and made to work together. In this episode, we provide an overview of the key topics covered in this domain, including network devices like switches and routers, wireless access points, and firewall configurations. You'll learn how network architecture is applied, how traffic is segmented using VLANs and trunks, and how link redundancy and failover contribute to a resilient infrastructure.

We also preview what it means to work with both wired and wireless technologies, explore the differences between local, cloud, and hybrid connectivity, and introduce the idea of integrating specialized network appliances. This domain is all about putting the network together and understanding how each layer fits. Whether you’re installing gear in a rack or remotely configuring cloud links, the concepts in Domain 2 bring theory into operational reality.
