Which following best describes an attack type that attempts to exhaust the amount of legitimate requests the server can maintain?

A.
Teardrop flood

B.
Fragment flood

C.
SYN flood

D.
TCP flood

Explanation:
A SYN flood is where attackers send fake SYN requests to servers in an attempt to exhaust the amount of legitimate requests the server can maintain. If the attacker is successful, the server will wait for a predetermined timeout period for the bogus connections to complete and most legitimate requests will be ignored by the server.
