Which of the following are true about a LAN-connected TCP/IP host and its IP routing (forwarding) choices?
- The host always sends packets to its default gateway.
- The host never sends packets to its default gateway.
- The host sends packets to its default gateway if the destination IP address is in a different subnet than the host.
- The host sends packets to its default gateway if the destination IP address is in the same subnet as the host.
Explanation: IPv4 hosts generally use basic two-branch logic. To send an IP packet to another host on the same IP network or subnet that is on the same LAN, the sender sends the IP packet directly to that host. Otherwise, the sender sends the packet to its default router (also called the default gateway).
