4. Question This PDU is found at the Transport Layer Transport Layer 100 A: What is Segment?

5. Question A: What are TCP (Transmission Control Protocol and UDP User Datagram Protocol)? These two protocols are found at the Transport Layer. Transport Layer 200

6. Question A: What is multiplexing? Segmentation allows these different types of communication stream to exist on the same media.. Transport Layer 300

7. Question A: What is a socket? The combination of port numbers and IP addresses is know as this. Transport Layer 400

8. Question A: What are source port, destination port and checksum? These three fields are found in all Transport Layer headers Transport Layer 500

9. Question A: What is the three-way handshake? TCP uses this to establish a connection. TCP 100

10. Question A: What is an ACK? This is sent to indicate that a packet has been received. TCP 200

11. Question What is Window size? This field is used for flow control. TCP 300

12. Question A: What are the SYN (synchronous number) and the ACK (the acknowledgement number)? These two fields contain numbers that are used to ensure the delivery of all packets in a conversation TCP 400

13. Question A: What is a FIN control flag? This flag is set in the segment header to terminate a TCP session TCP 500

14. Question A: What is connectionless? UDP is referred to as this type of communication. UDP 100

15. Question A: What is the application? UDP 200 Reassembly of packets are handled by this.

16. Question A: What is no acknowledgement sent. Considered best effort delivery? UDP 300 UDP is considered to be unreliable because of this feature.

17. Question A: What is it just sends it without any notification. A client starts UDP communication in this manner. UDP 400

18. Question A: What is the application would have to resend the data? This would happen at the application layer if the first packet of a UDP session is not received. UDP 500

19. Question A: What DNS (Domain Name Service)? 53 Port # 100

20. Question A: What is 25? This is the port number for SMTP Port # 200

21. Question A: What are the port numbers used for FTP? 20 and 21 Port # 300

22. Question A: What is 443? This port number is used for secure encrypted web page communication Port # 400

23. Question A: What are registered port numbers? 1024 - 49151 Port # 500

24. Question A: What is UDP? IP telephony uses this transport layer protocol. TCP or UDP 100

25. Question A: What is TCP? HTTP uses this transport layer protocol? TCP or UDP 200

26. Question A: What is TCP? This is considered to be a connection- oriented session. TCP or UDP 300

27. Question A: What is UDP? Video would use this type of protocol. TCP or UDP 400

28. Question A: What is UDP or TCP? DNS (Domain Name Service) can use this. TCP or UDP 500

29. Question A: What is 0 – 1023? These port numbers are used for well known applications. Potpourri 100

30. Question A: What is UDP? This protocol does only error detection not error correction Potpourri 200

31. Question A: What is 3,4,5,6 A device in a TCP session sends segments 1,2,3,4 with a window size 4 but only 1,2, and 4 are received. After receiving an ACK the device will send these packets. Potpourri 300

32. Question A: What is a random number? Source port numbers are set in this manner. Potpourri 400

33. Question A: What is 21? Based on this figure, this value will be entered in the ACK of the returning segment. Potpourri 500

34. Question A: What is connection-oriented (establishing sessions), reliable delivery, ordered Data reconstruction (same order) delivery, and flow control? These are the four functions of the Transmission Control Protocol Final Jeopardy 100 200 300 400 500
