Your network infrastructure is under a SYN ood attack. The attacker has crafted an automated botnet to simultaneously send 's' SYN packets per second to the server. You have put measures in place to manage 'f' SYN packets per second, and the system is designed to deal with this number without any performance issues. If 's' exceeds 'f', the network infrastructure begins to show signs of overload. The system's response time increases exponentially (2^k), where 'k' represents each additional SYN packet above the 'f' limit. Now, considering 's=500' and different 'f' values, in which scenario is the server most likely to experience overload and significantly increased response times?

Your network infrastructure is under a SYN ood attack. The attacker has crafted an automated botnet to simultaneously send 's' SYN packets per second to the server. You have put measures in place to manage 'f' SYN packets per second, and the system is designed to deal with this number without any performance issues. If 's' exceeds 'f', the network infrastructure begins to show signs of overload. The system's response time increases exponentially (2^k), where 'k' represents each additional SYN packet above the 'f' limit. Now, considering 's=500' and different 'f' values, in which scenario is the server most likely to experience overload and significantly increased response times?

A. f=510: The server can handle 510 SYN packets per second, which is greater than what the attacker is sending. The system stays stable, and the response time remains unaffected.

B. f=495: The server can handle 495 SYN packets per second. The response time drastically rises (2^5 = 32 times the normal), indicating a probable system overload.

C. f=505: The server can handle 505 SYN packets per second. In this case, the response time increases but not as drastically (2^5 = 32 times the normal), and the system might still function, albeit slowly.

D. f=490: The server can handle 490 SYN packets per second. With 's' exceeding 'f' by 10, the response time shoots up (2^10 = 1024 times the usual response time), indicating a system overload.
