CompTIA Network+ (N10-008) — Question 384

A non-employee was able to enter a server room. Which of the following could have prevented this from happening?

Answer options

• A. A security camera
• B. A biometric reader
• C. OTP key fob
• D. Employee training

Correct answer: B

Explanation

The correct answer is B, a biometric reader, as it requires unique physical characteristics for access, making it difficult for non-employees to enter. While A (security camera) can provide monitoring, it does not prevent access. C (OTP key fob) can enhance security but may not be as effective as biometric systems in controlling physical access. D (Employee training) is important but does not directly prevent unauthorized access.
