PrepAway - Latest Free Exam Questions & Answers

A.
Iris scanning plus fingerprint scanning

B.
Terminal ID plus global positioning system (GPS)

C.
A smart card requiring the user’s PIN

D.
User ID along with password

Explanation:
A smart card addresses what the user has. This is generally used in conjunction with testing what the user
knows, e.g., a keyboard password or personal identification number (PIN). Proving who the user is usually
requires a biometrics method, such as fingerprint, iris scan or voice verification, to prove biology. This is not a
two-factor user authentication, because it proves only who the user is. A global positioning system (GPS)
receiver reports on where the user is. The use of an ID and password (what the user knows) is a single-factor
user authentication.
