| Traditionally, Network Engineers used to be able to narrow their attention to just one thing: the network. This is a broad field that covers subfields such as hardware (routers, hubs, gateways, etc.), networking technologies (routing protocols, QoS, etc.), and network troubleshooting. Engineers can now install and debug advanced networking systems thanks to these abilities. However, creating and implementing such intricate networks is labor-intensive and time-consuming. CCNA DevNet was developed as a solution to this problem.
