- A
SMS passcode
Why wrong: SMS is not a primary Duo MFA method; Duo uses push, TOTP, phone callback, etc.
- B
Push notification
Duo Mobile push is a common MFA method for admin access.
- C
TOTP (time-based one-time password)
TOTP codes from an authenticator app are another Duo MFA method.
- D
Biometric fingerprint
Why wrong: Biometrics are not natively integrated with Duo for admin access; Duo uses app-based methods.
- E
Bypass code
Why wrong: Bypass codes are for occasional use when other methods are unavailable, not a primary MFA method.
Question 335 of 1,000
350-701 Endpoint Security and Identity Practice Question
This 350-701 practice question tests your understanding of endpoint security and identity. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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.)
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

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.

Biometric fingerprint
Why it's wrong here

- ✗
Bypass code
Why it's wrong here
Bypass codes are for occasional use when other methods are unavailable, not a primary MFA method.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
Cisco Duo integrates with network devices via RADIUS or SSH proxy, intercepting authentication requests and challenging the user with a push notification or TOTP. TOTP (RFC 6238) generates a 6-digit code that changes every 30 seconds, synchronized between the Duo Mobile app and the Duo server, providing offline-capable MFA. In real-world deployments, push notifications are preferred for their low friction, while TOTP serves as a fallback when network connectivity to Duo's cloud is intermittent.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 350-701 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
