CompTIA A+ Core 2 (220-1202) — Question 19

Which of the following describes a vulnerability that has been exploited before a patch or remediation is available?

Answer options

• A. Spoofing
• B. Brute-force
• C. DoS
• D. Zero-day

Correct answer: D

Explanation

The correct answer is D, Zero-day, which specifically refers to vulnerabilities that are exploited before developers have the opportunity to release a patch. Options A (Spoofing), B (Brute-force), and C (DoS) describe different types of attacks or methods but do not specifically relate to the timing of a vulnerability's exploitation in relation to available fixes.
