Refer to the exhibit. Host A is connected to the LAN, but it cannot get access to any resources on the Internet. The configuration of the host is shown in the exhibit. What could be the cause of the problem?

For a host to communicate with devices outside its local network, it must have a default gateway configured within its own subnet. If the default gateway IP address is on a different subnet than the host's IP address, the host cannot send traffic to it because Layer 2 communication (ARP) would fail. The gateway must be reachable at the data link layer, which requires being on the same broadcast domain.
