Refer to the exhibit.
After HostA pings HostB, which entry will be in the ARP cache of HostA to support this
transmission?
A.
Exhibit A
B.
Exhibit B
C.
Exhibit C
D.
Exhibit D
E.
Exhibit E
F.
Exhibit F
Explanation:
When a host needs to reach a device on another subnet, the ARP cache entry will be that of the
Ethernet address of the local router (default gateway) for the physical MAC address. The
destination IP address will not change, and will be that of the remote host (HostB).
The correct answer is “D”
Try today, 1000/1000….
I agree with Davide. The correct answer is “D”.
D will never be the correct answear. Because the ping IP-Address have to be the ones from Host B
“F” I think because when it pings HostB,,first it will check out if hostB is available in the local network and that local network is the switch which will then decide to forward it to the router because HostB isn’t available on LAN.
Host A knows host B is in another network so it will send the pings to its default gateway 192.168.6.1. Host A sends a broadcast frame asking the MAC address of 192.168.6.1. These information (IP and MAC address of the default gateway) is saved in its ARP cache for later use.
D is correct
No puede ser enviada la trama con la dirección MAC de la misma interfaz de donde se origino, y la dirección IP se mantiene porque es la misma red, por tanto la respuesta correcta seria la A.
i think E should be correct answer.
After a little google searching, it appears D is the correct answer.

After conferring with my colleagues and rereading the article, A is the correct answer. Host A will only see the MAC of router 1. The MAC changes every hop. The dest. IP will never change.
D is the correct Answer
this is the proccess:
1) PC A sends a broadcast ARP , because it doesn’t know R1’s mac-address
ARP Request:
source ip:192.168.6.27
source man: .fd86
target ip: 192.168.6.4
target mac: ???
2) R1 receives and sends an Unicast Arp reply
ARP Reply:
source ip:R1’s ip
source man: R1’s Mac
target ip: pc A’s ip
target mac: pc A’s mac
I just replicated in packet tracer.
You can see the ARP list in the HOST with “arp -a”
D is correct, ARP list will store default gateway ip and MAC.
Head ache LoL
