Test: DP: Transport Layer - Question 5

Port number used by Network Time Protocol(NTP) with UDP is

Detailed Solution: Question 5

Answer: b
Explanation: Port number used by Network Time Protocol with UDP is 123.

Test: DP: Transport Layer - Question 6

what is the header size of UDP packet?

Detailed Solution: Question 6

Answer: a
Explanation: The fixed size of the UDP packet header is 8 bytes.

Test: DP: Transport Layer - Question 7

The port number is “ephemeral port number”, if the source host is ……

Detailed Solution: Question 7

Answer: d
Explanation: If the source host is the client, the port number in most cases will be ephemeral port number.

Test: DP: Transport Layer - Question 8

“Total length” field in UDP packet header is the length of

Detailed Solution: Question 8

Answer: d
Explanation: Total length is the 16 bit field which contains the length of UDP header and the data.

Test: DP: Transport Layer - Question 9

Correct expression for UDP user datagram length is

Detailed Solution: Question 9

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.

Test: DP: Transport Layer - Question 10

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

Detailed Solution: Question 10

Answer: b
Explanation: Checksum field is used to detect errors over the entire user datagram.
