6.4-9 Network- and Link-layer addressing: an end-to-end-scenario (2c). 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 A to node C. Match the
source/destination network- or link-layer address at the location (6) by choosing a value from the
pulldown list. (Note: You can find more examples of problems similar to this here B.]
