Which of the following could be used as a second component of multifactor authentication if a user has an RSA token? A. Access card B. USB thumb drive C. Retina scan D. RFID
Correct Answer: C

Explanation: A retina scan could be used in conjunction with an RSA token because it is a biometric factor, and thus a different type of factor. An access card, RFID, and USB thumb drive are all items in possession of a user, the same as an RSA token, and as such would not be appropriate.
