CompTIA ITF+ (FC0-U61) — Question 51

Which of the following is an example of multifactor authentication?

Answer options

• A. Password and passphrase
• B. Fingerprint and retina scan
• C. Hardware token and smartphone
• D. Smart card and PIN

Correct answer: D

Explanation

The correct answer is D, as it involves two separate factors: something you have (smart card) and something you know (PIN). Options A, B, and C do not combine different authentication factors; A uses two knowledge-based factors, B uses two biometric factors, and C includes two possession factors, which does not qualify as multifactor authentication.
