SSCP Practice Question: Which TWO of the following are examples of…
Which TWO of the following are examples of biometric authentication? (Choose two.)
⚠ Common exam trap
ISC2 often tests the distinction between authentication factors (something you know, have, or are) and tricks candidates into selecting smart cards or PINs as biometrics because they are commonly associated with security, but they are not based on biological traits.
Answer choices
Why each option matters

Correct answer & explanation
✓
Retina scan
Retina scan is a biometric authentication method because it uses unique physiological characteristics of the eye's retinal blood vessel pattern to verify identity. Biometric authentication relies on measurable biological traits, and the retina's pattern is highly distinctive and difficult to replicate, making it a strong form of authentication.
