Wait, is this a trick question? Does the ARP cache come with a complimentary crystal ball to predict the future MAC addresses of hosts? I'm going with D, but I'm keeping an eye out for any unexpected magical powers.

Cecil: Nope, just matches IP addresses to MAC addresses on the same subnet.

User 1: I think the ARP cache just resolves the MAC address of a host given its IP address.

I'm going to go with D, but honestly, I'm just hoping I don't get any trick questions about arp dancing or something. You never know with these certification exams!

C? Really? ICMP messages? What does that have to do with ARP? Nah, I'm picking D and hoping the exam writers know what they're talking about.

Definitely going with D on this one. ARP cache is all about resolving MAC addresses.

Yeah, I agree. ARP is all about mapping IP addresses to MAC addresses. D makes the most sense.

I think D is the correct answer. It resolves the MAC address of a host device given its IP address.

I'm not sure about that. I think it adds only an IP address entry for an unknown device on the same subnet, so I would go with option B.

I agree with you, Kina. That's why I would choose option D.

Hmm, B does sound a bit too specific. I mean, an ARP cache is going to have both IP and MAC addresses, not just IP. Gotta go with D on this one.

Yeah, B does seem too limited. D is definitely the right choice here.

I'm not sure, but I think option A also makes sense as it maps an unknown IP address to a known hardware address.

D seems like the obvious choice here. ARP is all about resolving MAC addresses from IP addresses, right? I can't imagine why anyone would think it's for ICMP messages or adding IP addresses.
