Consider the figure below. The IP and MAC addresses are shown for nodes A, B, C and D, as well as for the router's interfaces Consider that B and C have already communicated before and assume that a new IP datagram is being sent from node B to node C. While this packet is traveling, indicate: 1. What is the source MAC address at point 3? 2. What is the destination MAC address at point 3? 3. What is the source IP address at point 3? 4. What is the destination IP address at point 3? 5 What is the source MAC address at point 2? F9-A4-SB-FD-BC-S9? 6. What is the destination MAC address at point 27 D9-FF-7D-FC-E8-67 7. What is the source MAC address at point 4? 8. What is the destination MAC address at point ? 9. Do the source and destination MAC addresses change at point 5? Answer with yes, no. or NA NO 10- Do the source and destination MAC addresses change at point 6? Answer with yes, no. or NA
