CISSP 问题一问

有条问题如下:

Access controls systems rely on Access Cards to provide identification and biometrics for authentication. What is it called?
A. Single-factor authentication
B. Two-factor authentication

Notes 话系 B. 但我觉得系 A 囉, 因为已写明 authentication 只系用紧biometrics 一种, access card 有用到不过系用黎做 identification

不知大家觉得是 A 还是 B?

The answer is B because something you have (the card) and something you are (biometric)
