[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.
