Question 5: In the diagram below, assume that host A wants to sends an IP datagram to the host C. Suppose all of the ARP tables in all nodes are up to date (8 points) (a) What is the destination IP address that A must use in the datagram? (b) What is the destination MAC address that A must use in the Ethernet frame? (c) What destination IP and MAC addresses must A use if the intended destination is B? (d) In general, how does any node know which destination MAC address to use in an Ethernet frame
