• Question 52:

  TCP is sending data in 5 segments with SEQ numbers 27000, 27500.28000, 28500, and 29000 respectively. During transmission, the segment with SEQ=28500 is dropped in the network. How does TCP handle this situation?

  A. The receiving end station sends an ACK flag with SEQ=28000 to indicate it has received a segment out of order.
  B. The receiving station sends a NACK frame with SEQ=28500 requesting that the frame be retransmitted
  C. Once the reciever's window is full. TCP assembles the payload and determines that SEQ=28500 is missing. At this point, the reciever sends the RST flag with SEQ=28500 to Request Single Transmission of the missing segment.
  D. TCP will collect the segments and forward them to the application layer where the SEQ numbers will be processed and a retransmit request will occur for the entire packet.
  A. The receiving end station sends an ACK flag with SEQ=28000 to indicate it has received a segment out of order.
