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.

I’m confused about the ARP table options; I thought it was only used for MAC addresses, but I can't recall the specifics.

I practiced a similar question, and I feel like it was about matching destination IPs too.

I think the correct answer might be B, since routers typically look up the destination IP to forward packets.
