Expert Solution
Step 1

The original datagram had a 4480-octet data field and a 20-octet header. Each frame can transport an IP datagram with a 20-octet header and 1480 data octets since the Ethernet frame can accommodate a payload of 1500 octets. Since 1480 is divisible by 8, we may utilize the largest frame size for all but the final piece. We require the following to fit 4480 data octets into frames that hold 1480 data octets:

3 datagrams × 1480 octets = 4440 octets, plus 1 datagram that carries 40 data octets (plus 20 IP header octets)
