About this MCQ

This Hard Cyber Security MCQ checks one syllabus fact.

The question is: “Which term refers to a software flaw that is exploited by attackers before the vendor releases a fix?”

The accepted answer is A. Zero-day vulnerability. Zero-day vulnerability is the person, body, or term that satisfies “Which term refers to a software flaw that is exploited by attackers before the vendor releases a fix” (option A). Option B (“Malware”) does not match the stem; it is a near-miss used to catch incomplete recall of Zero-day vulnerability. Option C (“Hashing”) does not match the stem; it is a near-miss used to catch incomplete recall of Zero-day vulnerability. Remaining alternatives (SQL injection) fall outside the same rule and should be eliminated once Zero-day vulnerability is identified. Cyber Security questions of this type reward precise definitions rather than approximate associations. Cyber Security recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
