Each interface is labeled with both an IP address and a MAC address. Imagine that host H1 (SRC) is sending a packet to host H2 (DST). Please answer the following questions about this figure: a) (2 pts] How many networks are shown above? b) (2 pts] Just before the packet reaches S1, what is its layer 2 destination? c) 12 ptsj Just before the packet reaches S2, what is its layer 2 source? d) (2 pts] Just after the packet leaves R2, what is its layer 3 source? e) [2 pts) When H1 sends out an ARP query, what is the reply to that query? f) [2 pts] Does the entry S2a.mac appear in Si's forwarding table? g) 2 pts] Will SRC's Ethernet device receive packets with destination R22.mac?
