Chapter 7 Intro To Networking

What is the complete range of TCP and UDP well-known ports?

0 to 1023

What range of ports can either be used by TCP to identify the requested service on the destination devices or as a client source port?

49152 to 65535

Fill in the blank using a number. A total of_______________messages are exchanged during the TCP session termination process between the client and the server.

Checksum: Both TCP and UDP Connectionless: UDP 3-way handshake: TCP Best for VoIP: UDP Port numbers:Both TCP and UDP Window size: TCP

What is a characteristic of UDP?

Connectionless

Which TCP header control bit is set on to terminate a TCP conversation?

FIN

What is an advantage that UDP has over TCP?

Low overhead

What is assigned by the transport layer to identify an application or service?

Port

Fill in the blank. TCP will normally retransmit lost data from the last successful acknowledgement. To allow the destination to acknowledge bytes in discontinuous segments and request retransmission of only the missing data, both hosts must be able to support an optional feature called ______________.

SACK, selective acknowledgements

During a TCP session, the____________________flag is used by the client to request communication with the server.

SYN

Which two flags in the TCP header are used in a TCP three-way handshake to establish connectivity between two network devices? (Choose two.)

SYN, ACK

Match each Application to its connectionless or connection-oriented protocol.

TFTP: UDP FTP: TCP HTTP: TCP DHCP: UDP Telnet: TCP

If a client sends an ISN of 2 to a server and a server responds with an ISN of 1 to the client, what is the final stage of the tcp three-way handshake?

The FTP client responds to the server with a smaller window size in the TCP header.

What are the primary purposes of the transport layer?(choose 3)

Tracking the individual communication between applications on the source and destination hosts, Segementing data for and reassembling segmented data into streams of application data at the destination, Identifying the proper application for each communication stream

What does UDP do when receiving messages that are more than one datagram in length?

UDP reassembles that data in the order it was received and passes it to the application.

Which of the following types of applications would use UDP? (choose 3)

VoIP, DHCP, TFTP

Which TCP header field specifies the number of segments that can be accepted before an acknowledgement is required?

Window Size

A host device sends a data packet to a web server via the HTTP protocol. What is used by the transport layer to pass the data stream to the proper application on the server?

destination port number

​What is a beneficial feature of the UDP transport protocol?

fewer delays in transmission

A host device needs to send a large video file across the network while providing data communication to other users. Which feature will allow different communication streams to occur at the same time, without having a single data stream using all available bandwidth?

multiplexing

________________ is the term used to describe the interleaving of data from multiple users on the same network.

multiplexing

Fill in the blank. Both TCP and UDP use ________ to separate multiple communications on the same channel.

port number, ports

Fill in the blank. A dynamic port in the range of 49152 to 65535 is also known as a(n) _______port.

private, ephemeral

Which two TCP header fields are used to confirm receipt of data?

sequence number, acknowledgment number

Which factor determines TCP window size?

the amount of data the destination can process at one time

What is a socket?

the combination of a source IP address and port number or a destination IP address and port number
