    Please help with the following problem. Provide step by step calculations.

    1. Which of the following is NOT true about the UDP header shown (in hexadecimal format): 
    06 32 00 0D 00 1C E2 17
    A. The destination port is 13 (decimal).
    B. All of the information given in the other answers is TRUE.
    C. The destination client process is the daytime service.
    D. The checksum for this UDP datagram has not been calculated and that field is not in use.
    E. The source port for the datagram is 1586 (decimal).

    2. A client uses UDP to send data to a server. The data payload is 26 bytes. Assuming no options, what is the percentage overhead considering both UDP and IP headers?
    A. 25.0%
    B. 43.5%
    C. 23.5%
    D. 51.8%

    1. UDP header format is as shown below.

    Source Port Number (16 bits) | Destination Port Number (16 bits)
    Length (UDP Header + Data) (16 bits) | UDP Checksum (16 bits)
    UDP Packet Data follows 9th byte onwards

    Given UDP ...
