What is the relevance of the default gateway address on a host that is transmitting to a destination for the first time?
Answer Options
The destination IP address is replaced with the default gateway when the destination is remote.
The host sends the default gateway packets that are deemed remote via a broadcast.
The host sends an ARP packet for the default gateway when the destination is remote.
The host creates a dedicated connection with the default gateway for remote traffic.
Correct Answer: C
Explanation
When traffic is remote to the immediate network, the host sends an ARP packet for the IP address of the default gateway. This determines the destination MAC address for the frame. The destination IP address is never replaced throughout the entire routing process. The host will not broadcast packets that are deemed remote; it will use the ARP process as described above. The host will not create a dedicated connection with the default gateway.
