Machine A $($with MAC address $00-01-02-$AA$-$BB$-$CC$)$ and Machine B $(00-01-02-$BB$-$CC$-$DD$)$ are on the same subnet. Machine C$,$ with address $00-01-02-$CC$-$DD$-$EE$,$ is on a different subnet. While the attacker is sniffing on the fully switched network, Machine B sends a message to Machine C$.$ If an attacker on Machine A wanted to receive a copy of this message, which of the following circumstances would be necessary?

Question $25$ options:

$1)$

The ARP cache of the router would need to be poisoned, changing the entry for Machine A to $00-01-02-$CC$-$DD$-$EE$.$

$2)$

The ARP cache of Machine B would need to be poisoned, changing the entry for the default gateway to $00-01-02-$AA$-$BB$-$CC$.$

$3)$

The ARP cache of Machine C would need to be poisoned, changing the entry for the default gateway to $00-01-02-$AA$-$BB$-$CC$.$

$4)$

The ARP cache of Machine A would need to be poisoned, changing the entry for Machine C to $00-01-02-$BB$-$CC$-$DD$.$
