ITPEC IP October 2021 Question 40
ITPEC IP October 2021 — Question 40 of 100
Iris, fingerprint, and vein characteristics are all biometrics, so II, III, and IV are correct. They authenticate a person using measurable physical traits. A PIN is information the user knows, not a bodily characteristic.
Answer (c)
Why not others:
- any set containing I incorrectly classifies a knowledge factor as biometric
- options omitting iris, fingerprint, or vein recognition leave out a valid biometric method
Key rule: Authentication factors are commonly categorized as something you know, have, or are; biometrics belong to the something-you-are category.
