Select all True statements! ( 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 acknowledgments to Host A because Host B cannot piggyback the acknowledgments on data. Ob) 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 is m, then the sequence number for the subsequent segment will necessarily be m + 1. O e) The TCP segment has a field in its header for rwnd. ( f) Suppose that the last SampleRTT 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 acknowledgment number is necessarily 42. Select all True statements! ( a) Host A is sending Host B a large file over a TCP connection.
