CompTIA Security+ (SY0-501) — Question 332

An organization plans to implement multifactor authentication techniques within the enterprise network architecture. Each authentication factor is expected to be a unique control.
Which of the following BEST describes the proper employment of multifactor authentication?

Answer options

• A. Proximity card, fingerprint scanner, PIN
• B. Fingerprint scanner, voice recognition, proximity card
• C. Smart card, user PKI certificate, privileged user certificate
• D. Voice recognition, smart card, proximity card

Correct answer: A

Explanation

The correct answer, A, includes a proximity card, a fingerprint scanner, and a PIN, which represent three different types of authentication factors: something you have, something you are, and something you know. The other options either include factors that are too similar or do not represent distinct categories of authentication, thereby failing to meet the multifactor requirement.
