Review 14: True or false? a. Host A is sending Host B a large file over a TCP connection. Assume Host B has no data to send Host A. Host B will not send acknowledgements to Host A because Host B cannot piggyback the acknowledgements on data.

b. The size of the TCP rwnd never changes throughout the duration of the connection.

c. Suppose Host A is sending Host B a large file over a TCP connection. The number of unacknowledged bytes that A sends cannot exceed the size of the receive buffer.

d. 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 m, then the sequence number for the subsequent segment will necessarily be m +1.

e. The TCP segment has a field in its header for rwnd.

f. Suppose that the last Sample RTT in a TCP connection is equal to 1 sec. The current value of TimeoutInterval for the connection will necessarily be 1 sec.

g. Suppose Host A sends one segment with sequence number 38 and 4 bytes of data over a TCP connection to Host B. In this same segment the acknowledgement number is necessarily 42.
