CompTIA Security+ (SY0-601) — Question 350

Which of the following is a physical security control that ensures only the authorized user is present when gaining access to a secured area?

Answer options

• A. A biometric scanner
• B. A smart card reader
• C. A PKI token
• D. A PIN pad

Correct answer: A

Explanation

The correct answer is A, a biometric scanner, as it uses unique biological traits for identification, ensuring that only authorized users can access the area. The other options, while they provide access control, do not inherently confirm the physical presence of the user like a biometric scanner does.
