Exam 9: Tcp/ip Transport Layer Protocols

TCP half-open connections occur when the handshake process does not end successfully with a final ACK.

Which of the following is a simple protocol that is used by applications that contain their own connection-oriented timeout values and retry counters, similar to those provided by TCP?

Which of the following is the overloading of the network or a receiver?

Which of the following processes guarantees that packets are ordered properly and protects against missing segments?

TCP keep-alives are enabled by default on Windows XP, Windows Vista, Windows 7, Windows Server 2003, and Windows Server 2008, although any application may disable TCP keep-alives, if desired by its programmer.

What are the functions of a connection-oriented protocol?

What is used in order for TCP hosts to create a virtual connection with each other?

Briefly define the following TCP flag settings: URG (Urgent), ACK (Acknowledgment), and PSH(Push).

Match each item with a statement below. a.timeout mechanism b.temporary port c.Time Wait delay d.TCP buffer area e.retransmission timer f.Nagle algorithm g.Sequence number tracking h.acknowledgment i.windowing -a port that is used for the duration of the connection

Once a TCP connection is established, which of the following can maintain the connection when there is no data sent across the wire?

The TCP connection termination process requires how many packets?

Match each item with a statement below. a.timeout mechanism b.temporary port c.Time Wait delay d.TCP buffer area e.retransmission timer f.Nagle algorithm g.Sequence number tracking h.acknowledgment i.windowing -the process of following the current sequence number sent by a TCP peer and sending an acknowledgment value to indicate the next-expected sequence number

What is the order of the half-open connection communication sequence?

A protocol that offers no built-in error-checking or retransmission capability uses which type of packet delivery?

Briefly describe the following TCP connection states: LISTEN, SYN SENT, SYN RECD, AND CLOSE WAIT.

Which of the following is used to indicate that the host completed a transaction?

Match each item with a statement below. a.timeout mechanism b.temporary port c.Time Wait delay d.TCP buffer area e.retransmission timer f.Nagle algorithm g.Sequence number tracking h.acknowledgment i.windowing -notification of successful receipt of data

Which of the following is caused when enough data is sent to a TCP host to fill its receiver buffer, thereby putting the receiver in a zero-window state.

Overloading a receiver occurs when the number of data bytes is greater than which of the following?

The ____________________ pseudo-header consists of three fields taken from the IP header: the IP Source Address field value, the IP Destination Address field value, and the Protocol field value.
