$7\mathrm{.}2$ Consider the following network diagram $($Figure Q$7)$ below: $/$ Beskou die volgende

network diagram $($Figuur V$7).$

Consider the following host devices with their respective IP and MAC addresses $($the MAC addresses

have been shortened$),/$ Beskou die volgende toostelle met hul onderskeie IP$-$ en MAC$-$adresse $($die

MAC$-$adresse is verkort$).$

Host A and B are connected to the router at port $192\mathrm{.}168\mathrm{.}1\mathrm{.}1($MAC: ee$01)$ via switch S$1/$ Toestel A

on B is via switch S$1$ aan die routerpoort $192\mathrm{.}168\mathrm{.}1\mathrm{.}1($MAC: $0$e$01)$ gekoppel.

Host A $(192\mathrm{.}168\mathrm{.}1\mathrm{.}2/$ aaaa$)$

Host B $(192\mathrm{.}168\mathrm{.}1\mathrm{.}3/.$bbbb$)$

Host C and D are connected to the router at port $172\mathrm{.}64\mathrm{.}1\mathrm{.}1($MAC: ee$02)$ via switch S$2/$ Toestel C

on D is via switch S$2$ aan die routerpoort $172\mathrm{.}64\mathrm{.}1\mathrm{.}1($MAC: $0002)$ gokoppol.

Host C $(172\mathrm{.}64,1\mathrm{.}2/.$ cocc$)$

Host D $(172,64,1,3/.$dddd$)$

Host A wants to send a packet to Host D on the network, but Host A does not know how to get to

Host $D$ to deliver to packet. Explain how the network would determine each hop to send the packet

from Host A to D$,$ using the ARP protocol.

As part of your answer, make sure to describe the packet exchange process between the hosts,
