[All 4A0-112 Questions]

Which of the following statements about the IP forwarding process on a router is TRUE?

Show Suggested Answer Hide Answer
Suggested Answer: B

During the IP forwarding process, routers use the routing table to determine the next hop based on the destination IP address. The source IP address is not directly involved in the lookup process for forwarding.

The ARP table is used to map IP addresses to MAC addresses, specifically for resolving the MAC address of the next hop (destination MAC address) for forwarding packets within the local network.

Wait, are we sure about that? I thought it was about the source IP too.

B is the correct answer! It looks for the destination IP.

I feel like A is definitely wrong since routers don’t care about the source IP for forwarding, but I’m not 100% sure about the others.

I practiced a similar question, and I think it was about how ARP helps with MAC addresses, but I can't remember if it was source or destination.

I’m not so sure, but I remember something about the routing table being crucial for determining where to send packets.

I think it’s B because routers forward packets based on the destination IP, right?
