Which device should be recommended for secure access to a central server room using a retinal scan?

• A. Password keypad
• B. Biometric scanner
• C. Smart card reader
• D. Facial recognition system

Answer: (B)

A biometric scanner is the most appropriate device for secure access to a central server room using a retinal scan. This technology specifically utilizes unique biological characteristics, such as fingerprints, facial recognition, or iris recognition, to identify individuals. In this case, a retinal scan is a highly secure form of biometric identification because it analyzes the patterns of blood vessels in the retina, which are unique to each person and difficult to replicate. Biometric systems, including retinal scanners, offer advantages over traditional security methods such as password keypads or smart card readers because they require physical traits that are inherently linked to the user, making it nearly impossible for unauthorized persons to gain access. This level of security is particularly critical in environments where sensitive data is stored, such as a server room. While other devices like smart card readers and facial recognition systems offer secure access solutions, they do not specifically use retinal scanning, making the biometric scanner the best match for the specified requirement.
