Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Time-based one-time password (TOTP)
Duo provides push notifications to a mobile app and time-based one-time passwords (TOTP) as authenticator methods. Biometrics is not a Duo method; SMS passcodes are available but legacy; hardware tokens are supported but the question asks for TWO, and push and TOTP are the most common. However, hardware token is also valid. The exam expects push and TOTP as primary.
