CompTIA Security+ (SY0-501) — Question 288

Which of the following would meet the requirements for multifactor authentication?

Answer options

• A. Username, PIN, and employee ID number
• B. Fingerprint and password
• C. Smart card and hardware token
• D. Voice recognition and retina scan

Correct answer: B

Explanation

The correct answer is B because it combines something you have (fingerprint) with something you know (password), fulfilling the multifactor requirement. Options A, C, and D do not combine different categories of authentication factors as effectively; for instance, A includes only knowledge factors, and C primarily involves possession factors.
