Network$-$ and Link$-$layer addressing: an end$-$to$-$end$-$scenario. Consider the network shown below. The IP and MAC addresses are shown for hosts A$,$ B$,$ C and D$,$ as well as for the router's interfaces. Consider an IP datagram being sent from node C to node A $($note: from right to left$).$ Match the source$/$destination network$-$ or link$-$layer address at the location $(6)$ by choosing a value from the pulldown list. Group of answer choices What is the source MAC address on the frame at point $(6)?[$ Choose $]$ What is the destination MAC address on the frame at point $(6)?[$ Choose $]$ What is the source IP address of the datagram at point $(6)?[$ Choose $]$ What is the destination IP address of the datagram at point $(6)?[$ Choose $]$
