Notice that ARP packets are sent in pairs, the first asking "Who has an IP address?" $($in this case, $192\mathrm{.}168\mathrm{.}1\mathrm{.}1)$ and telling the answer to $192\mathrm{.}18\mathrm{.}1\mathrm{.}20,$ and the second responding that $"192\mathrm{.}168\mathrm{.}1\mathrm{.}1$ is at$"$ some address. Given the topology diagram for this $($and every$)$ lab, what is this pair of ARP packets doing?

Question $2$ options:

a$)$

Trying to find the MAC address related to the IP address of the inside interface of the firewall

b$)$

Trying to find the MAC address related to the IP address of the Client PC

c$)$

Trying to find the MAC address related to the IP address of the inside interface of the firewall and report that answer back to the Client PC

d$)$

Trying to find the MAC address related to the IP address of the DMZ interface for the firewall and report that answer back to the Client PC
