CompTIA A+ 220-1102 (V14) Practice Question

The gateway in a network is a node that routes traffic from a local network to other networks or the internet. Configuring the correct gateway address enables the workstation to communicate with devices outside of its local subnet, such as the wider internet or other networks. The gateway address is typically provided by the network administrator or is obtained automatically if DHCP is used. A hostname would not serve as a path to external networks, and the subnet mask only identifies the local network range, not the gateway. Incorrect DNS settings would lead to name resolution issues, not necessarily connectivity problems to networks outside the local subnet.
