CompTIA Security+ (SY0-601) — Question 353

Which of the following best describes the situation where a successfully onboarded employee who is using a fingerprint reader is denied access at the company's main gate?

Answer options

• A. Crossover error rate
• B. False match rate
• C. False rejection
• D. False positive

Correct answer: C

Explanation

The correct answer is C, False rejection, which refers to a situation where a legitimate user is incorrectly denied access by the biometric system. The other options do not apply here; A (Crossover error rate) is a measure of the accuracy of biometric systems, B (False match rate) pertains to incorrect positive identifications, and D (False positive) indicates an unauthorized user being granted access, which is not the case in this scenario.
