Consider the network shown below. Suppose that source node A wants to send an IP datagram, encapsulated in an Ethernet frame to node H$.$ Before doing so$,$ A uses ARP to find H$$s MAC address. A then sends an Ethernet frame to H and H then sends a reply back to A$.$ Suppose that initially the switch tables are empty at all switches, and that all ARP tables are empty.

a$)$ Give the switch tables for S$1,$ S$2,$ S$3$ and S$4$ after the ARP request packet is received at H$.$

b$)$ How many of hosts A through F receive the ARP request?

c$)$ Give the switch tables for S$1,$ S$2,$ S$3$ and S$4$ after the ARP reply packet has been sent by H and has been received at A$.$

d$)$ Give the switch tables for S$1,$ S$2,$ S$3$ and S$4$ after the IP datagram has been sent by A and has been received at H$.$

e$)$ How many of hosts A through F receive the frame containing the A$-$to$-$H datagram?
