Quizplus · Accepted Answer

The gateway address is wrong because it must reside on the same network as the device.
Key Takeaway: The default gateway address is the address to which a device sends packets that are not destined for the same network the device is on. In other words, if a device is trying to communicate with another network, it sends the packets to a router, or gateway, on the same network for it to decide how to get the packets to the destination. In this example, the gateway address would have to be on the 192.168.4.x/24 network.
