Chapter 3 T/F



This activity contains 10 questions.

Question 1.
Consider an HTTP Web server using persistent connections. Suppose the server spawns a separate process for each client that connects to the server. Then each of these spawned processes will have different server port numbers.

   
 
End of Question 1


Question 2.
Host A is sending host B a large file over a TCP connection. Assume host B has no data to send A. Host B will not send acknowledgements to host A because host B cannot piggyback the acknowledgements on data.

   
 
End of Question 2


Question 3.
The size of the TCP RcvWindow never changes throughout the duration of the connection.

   
 
End of Question 3


Question 4.
Suppose host A is sending a large file to host B over a TCP connection. If the sequence number for a segment of this connection is m, then the sequence number for the subsequent segment will necessarily be m+1.

   
 
End of Question 4


Question 5.
The TCP segment has a field in its header for RcvWindow.

   
 
End of Question 5


Question 6.
Suppose that the last SampleRTT in a TCP connection is equal to 1 sec. Then Timeout for the connection will necessarily be set to a value >= 1 sec.

   
 
End of Question 6


Question 7.
Suppose host A sends host B one segment with sequence number 38 and 4 bytes of data. Then in this same segment the acknowledgement number is necessarily 42.

   
 
End of Question 7


Question 8.
Suppose that host A wants to send data over TCP to host B, and host B wants to send data to host A over TCP. Two separate TCP connections - one for each direction - are needed.

   
 
End of Question 8


Question 9.
The MSS is the maximum size of a TCP segment including headers.

   
 
End of Question 9


Question 10.
In TCP, the acknowledgement number that a host puts in a segment is the sequence number of the next byte the host is expecting from the sender.

   
 
End of Question 10
