350-701 Practice Question: Wants to implement multi-factor authentication…
An organization wants to implement multi-factor authentication (MFA) for administrative access to network devices. Which two methods can be used with Cisco Duo to provide MFA for admin access? (Choose two.)
⚠ Common exam trap
Cisco often tests the distinction between Duo-supported MFA methods (push, TOTP, phone callback) and methods that are either deprecated (SMS) or not directly supported (biometrics, bypass codes) for administrative access to network devices.
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
✓
Push notification
Push notification is correct because Cisco Duo can send a push notification to the Duo Mobile app on the administrator's smartphone. The admin approves or denies the login attempt directly from the app, providing a seamless and secure second factor for authentication to network devices.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SMS passcode
Why it's wrong here
SMS is not a primary Duo MFA method; Duo uses push, TOTP, phone callback, etc.
- ✓
Push notification
Why this is correct
Duo Mobile push is a common MFA method for admin access.
- ✓
TOTP (time-based one-time password)
Why this is correct
TOTP codes from an authenticator app are another Duo MFA method.
- ✗
Biometric fingerprint
Why it's wrong here
Biometrics are not natively integrated with Duo for admin access; Duo uses app-based methods.
- ✗
Bypass code
Why it's wrong here
Bypass codes are for occasional use when other methods are unavailable, not a primary MFA method.
