CompTIA A+ Core 2 (220-1102) — Question 660

Which of the following is an example of MFA?

Answer options

• A. Fingerprint scan and retina scan
• B. Password and PIN
• C. Username and password
• D. Smart card and password

Correct answer: D

Explanation

Option D is correct because it includes two different factors: something you have (smart card) and something you know (password). The other options consist of factors from the same category, either biometrics or knowledge-based authentication, which do not qualify as MFA.
