[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.

Definitely B, it matches the destination IP.

B, because who cares about the source IP when you're forwarding a packet? It's all about that destination, baby!

B is the way to go. Routing tables are for IP addresses, not MAC addresses. Easy peasy!

I feel like A is incorrect because the router doesn't care about the source IP for forwarding, but I'm not 100% confident.

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

I'm not entirely sure, but I remember something about the routing table being used for destination addresses, so B seems likely.

I'm not too sure about this. I know the routing table is involved, but I'm not sure if it's the source or destination IP address. Maybe I should review my notes on IP forwarding before answering.

I'm feeling confident about this one. The key is that the IP forwarding process is all about the destination, not the source. So B is the right answer.

Okay, I've got it. The router uses the routing table to find the destination IP address, and then the ARP table to find the corresponding destination MAC address. B is the correct answer.

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

B) It uses the routing table to find a match for the destination IP address.

Hmm, I'm a bit confused. I thought the router used the routing table for both the source and destination IP addresses. Let me think this through again.

I'm pretty sure it's B. The router uses the routing table to find the destination IP address and then looks up the corresponding MAC address in the ARP table.
