Question 2 (10 points) Draw the Layer 2, Layer 3, Layer 4 and Application Layer packets of the Wireshark trace. You don't need to show all the details of the header fields, but make sure to show the sizes of headers and payload and when the total number of bytes (72 bytes on wire) came from. (5 points) This Wireshark packet is a DNS query. Suppose the link has a data rate of 100 Mbps. What is the transmission delay of this packet?
