82. One of the most famous documented dDoS attacks Back. How does the Back work?
A. The client asks for a service by sending a request with many HTTP headers resulting Apache Web server to crash
B. Attack is launched against an apache Web server, which is flooded with requests containing a large number of front-slash ( / ) characters in the URL.
C. The attacker sends the victim a malformed GET request, which can crash the Web server.
D. The attacker sends the victim a TCP SYN packet that contains the same IP address as the source and destination addresses. Such a packet completely locks the victim's system.
E. The victim's mail queue is flooded by an abundance of messages, causing system failure.
