Question 1

A TCP segment begins with octet 8,658 and ends with octet 12,783.What number does the receiving host put in the acknowledgment number field of the TCP segment that acknowledges this TCP segment?&#10;A)8,658&#10;B)8,659&#10;C)12,783&#10;D)12,784

Accepted Answer

The acknowledgment number field in a TCP segment contains the sequence number of the next expected byte. Therefore, the receiving host will put 12,784 in the acknowledgment number field since it is the next expected byte after the received segment (which ends with octet 12,783).

Question 2

A TCP segment carries data octets 456 through 980.The following TCP segment is a supervisory segment carrying no data.What value is in the sequence number field of the latter TCP segment?&#10;A)456&#10;B)457&#10;C)980&#10;D)981

Accepted Answer

Since the supervisory segment carries no data, the sequence number of the next expected byte is the value in the next sequence number field. Therefore, the sequence number field of the latter TCP segment would be 981.

Question 3

Flow control in TCP depends on the ________ field.&#10;A)acknowledgement number&#10;B)window size&#10;C)both A and B&#10;D)neither A nor B

Accepted Answer

TCP uses both the acknowledgement number and window size fields for flow control. The acknowledgement number indicates the number of bytes that have been successfully received by the other end of the connection, while the window size field indicates the amount of unused buffer space that is available to receive additional data. Together, these fields allow TCP to regulate the amount of data that is being sent at any given time to prevent overloading the network or overwhelming the receiver.

Question 4

A TCP segment begins with octet 8,658 and ends with octet 12,783.What number does the sending host put in the sequence number field?&#10;A)8,658&#10;B)8,659&#10;C)12,783&#10;D)12,784

Accepted Answer

The answer of A TCP segment begins with octet 8,658...
