QUESTION 21:
When files are transferred between a host and an FTP server, the data is divided
into smaller pieces for transmission. As these pieces arrive at the destination host,
they must be reassembled to reconstruct the original file. What provides for the
reassembly of these pieces into the correct order?
A. The sequence number in the TCP header
B. The Start Frame Delimiter in the 802.3 Preamble
C. The TTL in the IP header
D. The acknowledgement number in the segment header
E. The frame check sequence in the Ethernet frame trailer

Answer: A
Explanation:
The Transport layer can provide reliable networking via acknowledgments, sequencing,
and flow control.
Acknowledgments Delivered segments are acknowledged to the sender. If they are not
acknowledged, the sender will retransmit.
* Sequencing Data segments are sequenced into their original order when they arrive at
the destination.
* Flow Control Provides buffer controls that prevent packet flooding to the destination
host. Buffers store bursts of data for processing when the transmission is complete.
Layer 4 protocols include the following:
* Transmission Control Protocol (TCP)
* User Datagram Protocol (UDP)
Sequenced Packet Exchange (SPX)A reliable communications protocol created by
Novell NetWare
QUESTION 22:
Network equipment supporting the use of flow control mechanisms has been
recently installed in the PassGuide network. What is the purpose of flow control in a
data network?
A. It ensures that data is retransmitted if an acknowledgment is not received.
B. It reassembles segments in the correct order on the destination device.
C. It provides a mechanism for the receiver to control the transmission speed.
D. It regulates the size of each datagram segment.
E. All of the above are functions of flow control
Answer: C
Explanation:
Flow control paces the transmission of data between a sending device and a receiving
device. Flow control ensures that the receiving device can absorb the data sent to it
before the sending device sends more. When the buffers on the receiving device are full,
a message is sent to the sending device to suspend transmission until the data in the
buffers has been processed.
Incorrect Answers:
A. Data retransmission mechanisms are not handled by control. They are most often
handled by transport layer protocols such as TCP.
B. This describes the reassembly portion of the segmentation and reassembly (SAR)
function of network equipment.

D. The maximum transmission unit (MTU) handles the regulation of maximum frame
sizes.
QUESTION 23:
You need to describe the various types of flow control to your co-workers. Which of
the following are types of flow control that can be used in a network? (Choose three)
A. Congestion avoidance
B. Windowing

D. Buffering
E. Load Balancing
F. Fast Forward
Answer: A, B, D
QUESTION 24:
Part of the PassGuide network is displayed below:
Study the exhibit shown above. Host PassGuide A has established a connection with
the PassGuide II server attached to interface E0 of the PassGuide 2 router. Which of
the following statements describe the information contained in protocol data units
sent from Host PassGuide to PassGuide II? (Choose three)
A. The destination port number in a segment header will have a value of 80
B. The destination IP address of a packet will be the IP address of the E0 interface of the
PassGuide 1 router
C. The destination IP address of a packet will be the IP address of the network interface
of the PassGuide II server
D. The destination address of a frame will be the MAC address of the E0 interface of
PassGuide 1 router
