Exercise 2

A DHCP packet is encapsulated in a UDP packet, which is encapsulated in an IP packet, which is encapsulated in an Ethernet frame. Find the efficiency of a DHCP packet when no option is used. The efficiency in this case is measured in the number of bytes in the DHCP packet to the total number of bytes transmitted at the data link layer.
