1. Why is flow control used for TCP data transfer?
* to synchronize and order sequence numbers so data is sent in complete numerical order
* to synchronize window size on the server
* to prevent the receiver from being overwhelmed by incoming data
* to synchronize equipment speed for sent data

2. Why are port numbers included in the TCP header of a segment?
* to enable a receiving host to forward the data to the appropriate application
* to identify which switch ports should receive or forward the segment
* to allow the receiving host to assemble the packet in the proper order

* to determine which Layer 3 protocol should be used to encapsulate the data
* to indicate the correct router interface that should be used to forward a segment

3. Which OSI model layer is responsible for regulating the flow of information from source to destination, reliably and accurately?
* network
* presentation
* application
* transport
* session

4. Based on the transport layer header shown in the diagram, which of the following statements describe the established session? (Choose two.)
* This is a UDP header.
* This contains a Telnet request.
* This contains a TFTP data transfer.
* The return packet from this remote host will have an Acknowledgement Number of 43693.
* This is a TCP header.

5. Refer to the exhibit. Host A is using FTP to download a large file from Server 1. During the download process, Server 1 does not receive an acknowledgment from Host A for several bytes of transferred data. What action will Server 1 take as a result?
* change the window size in the Layer 4 header
* create a Layer 1 jam signal
* reach a timeout and resend the data that needs to be acknowledged
* send a RESET bit to the host
6. What mechanism is used by TCP to provide flow control as segments travel from source to destination?
* session establishment
* window size
* sequence numbers
* acknowledgments

7. Which two options represent Layer 4 addressing? (Choose two.)
* identifies multiple conversations between the hosts
* identifies the devices communicating over the local media

* identifies source and destination hosts
* identifies the destination network
* identifies the communicating applications

8. With TCP/IP data encapsulation, which range of port numbers identifies all well-known applications?
* 1024 to 2047

* 0 to 255
* 49153 to 65535
* 256 to 1022
* 0 to 1023

9. Which information is found in both the TCP and UDP header information?
* acknowledgments
* sequencing
* flow control
* source and destination

10. Refer to the exhibit. In line 7 of this Wireshark capture, what TCP operation is being performed?
* Bottom of Form
* segment retransmit
* session disconnect
* data transfer
* session establishment

11. Which event occurs during the transport layer three-way handshake?
* The server acknowledges the bytes of data received from the client.
* UDP establishes the maximum number of bytes to be sent.
* The two applications exchange data.
* TCP initializes the sequence numbers for the sessions.
12. After a web browser makes a request to a web server that is listening to the standard port, what will be the source port number in the TCP header of the response from the server?
* 1728
* 53
* 80
* 13
* 1024
13. Refer to the exhibit. What two pieces of information can be determined from the output that is shown? (Choose two.)
* The local host is using well-known port numbers to identify the source ports.
* Communication with 64.100.173.42 is using HTTP Secure.
* 192.168.1.101:1042 is performing the three-way handshake with 128.107.229.50:80.

* The local computer is accepting HTTP requests.
* A termination request has been sent to 192.135.250.10.

14. What is dynamically selected by the source host when forwarding data?
* source physical address
* source port
* default gateway address
* destination logical address

15. What are two features of the User Datagram Protocol (UDP)? (Choose two.)
* sequence and acknowledgements
* low overhead
* connection-oriented
* connectionless
* flow control

16. Which transport layer protocol provides low overhead and would be used for applications which do not require reliable data delivery?
* DNS
* TCP
* HTTP
* IP
* UDP

17. Which three features allow TCP to reliably and accurately track the transmission of data from source to destination?
* best effort delivery

19. During a TCP communication session, if the packets arrive to the destination out of order, what will happen to the original message?
* The packets will be delivered and reassembled at the destination.
* The packets will be retransmitted from the source.
* The packets will be delivered and not reassembled at the destination.
* The packets will not be delivered.
