9. [10 points) Recall our discussion on IP and MAC addressing. Now consider the network diagram below. Let a packet start from Host A and travel through two routers to Host B. a. [4 points) Fill out the blank fields in the packet header at each traversed interface. (Note: no need to write down the whole MAC; just fill out the 6th byte) 3.3.3.2 B 1.1.12 FF FF FF FF FF-55 3.3.3.2 FF FF FF FF FF-ZA 2.2.2.1 FF-FF-FF-FF-FF-9B 3.3.3.1 FF-FF-FF-FF-FF-3A 3.3.3.3 FE TE TE TE TE = 131.1.3 FF-FF-FF-FF-FF-70 22.2.2 FF-FF-FF-FF-FF-3B FF-FF-FF-FF-FF-4B b. 12 points) How did the source host A determine the destination IP address of B? 1. DNS ii. DHCP ii. ARP iy, HTTP c. 12 points) Which interface's MAC address will host A use to fill out the "dst MAC address field in the departing packet. i. Router interface with IP 2.2.2.1 ii. Router interface with IP 1.1.1.1 iii. Router interface with IP 3.3.3.1 iv. Router interface with IP 2.2.2.2 d. [2 points) What protocol did host A use to determine which address to put in the "dst MAC" field of the departing packet? i. DNS ii. HTTP iii. ARP iv. ICMP
