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

acknowledgment number sequence number

Which factor determines TCP window size?

the amount of data the destination can process at one time

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

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

What is a characteristic of UDP?

Connectionless

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

FIN

What are the primary purposes of the transport layer?

Identifying the proper application for each communication stream 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

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

SYN ACK

Match the characteristics to the protocol category: Window size Checksum Connectionless Best for VoIP Port numbers 3-way handshake

TCP Both TCP and UDP UDP UDP Both TCP and UDP TCP

Which of the following types of applications would use UDP?

TFTP DHCP VoIP

A client is downloading a large file from a server using FTP. One of the segments is lost during transit. What will happen?

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

Match each application to its connectionless or connection-oriented protocol. TFTP Telnet DHCP FTP HTTP

UDP TCP UDP TCP TCP

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 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

What is a socket

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