Explanation:
(A) a prepared application that takes advantage of a known weakness:
Correct. This is the definition of a security exploit. It targets vulnerabilities in software or systems to perform unauthorized actions.
(B) a tool used to quickly check computers on a network for known weaknesses:
This describes a vulnerability scanner, not an exploit.
(C) an application that captures TCP/IP data packets…:
This refers to a packet sniffer or network sniffer, which may be used maliciously but is not itself an exploit.
(D) a situation in which one person or program successfully masquerades as another…:
This describes spoofing, a form of attack, but not specifically a security exploit.
Conclusion:
(A) best defines a security exploit.
