All of DU failing, path MTU discovery, and congestion control / source quench might be the right / expected answer, 
which makes this a not great question.  DU doesn't break TCP per se but would hang sessions until timeout; path MTU 
isn't a TCP function per se, though it uses TCP as the probe.  Source quench is only a small fraction of the TCP 
congestion control solution space now.

My systems consulting company uses a HR prescreen of 20 questions.  It took a team of senior consultants and HR some 
years to tune the questions in.  They need to be clear, have unambiguously correct answers, the answer correctness 
needs to be obvious to the HR / recruiter who isn't technical.  

I think this one fails to have an unambiguously correct answer and an answer the non-tech recruiter / HR person will 
understand.  So, probably time for a better question...
