Question 1 Not yet Consider the network shown above. Assume ARP caches at the hosts and routers are empty initially and each host knows the IP addresses of all other hosts. answered Ethemet Marked out of 5.00 Host IT Host I 3 1:2:1 5:6e:7d 140.160.91 Flag question 131.12.16.50 PPP .5 131.12.16 Ethernet Router 0:0:6:fef:3d 13:2f:6e:58:4d:la 0:1:6:5:32:47 Host III .4 Note that IP subnet addresses are three-byte numbers such as 131.12.16, and the host IDs are indicated on each interface, such as 3 for host I. Thus, for example, the IP address of Host I's interface is 131.12.16.3. The Ethernet MAC addresses are also shown next to each interface. Consider that (Host I) sends an IP datagram (of data) to (Host III), answer the following question: a. Who sends the ARP request? What is the MAC address of the destination? Select one: O a. sender= Host I, MAC address of the destination=1:2:1:5:6E:7D O b. sender= Host III, MAC address of the destination=1:2:1:5:6E:7D O c. sender= Host I, MAC address of the destination=FF:FF:FF:FF:FF:FF O d. sender- Host III, MAC address of the destination=FF:FF:FF:FF:FF:FF
