When setting up a new network, which of the following should be configured first?

Configuring the router first is essential when setting up a new network because the router serves as the central hub that manages traffic between different networks, such as a local area network (LAN) and the internet. It establishes the foundational pathway for data to flow, ensuring that devices on the network can communicate both internally and externally.

Once the router is properly configured with the necessary network settings, such as IP address assignment and security features, other devices like switches, firewalls, and workstations can be integrated into the network architecture. This sequence allows for a properly structured and functioning network where all components work seamlessly together.

Workstations, firewalls, and switches rely on the router for connectivity and successful data transmission, hence they need to be configured only after the router is operational. The firewall may later be set up to enhance security, while switches are used to connect multiple devices within the local network. Therefore, establishing the router as the first step is crucial for the entire network's functionality.
