Correct expression for UDP user datagram length is

Solution:

Answer: a
Explanation: A user datagram is encapsulated in an IP datagram. There is a field in the IP datagram the defines the total length. There is another field in the IP datagram that defines the length of the header. So if we subtract the length of a UDP datagram that is encapsulated in an IP datagram, we get the length of UDP user datagram.

QUESTION: 10

The field used to detect errors over the entire user datagram is

Solution:

Answer: b
