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 VPN access using Cisco AnyConnect and Duo. Which TWO authentication factors can Duo provide? (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
✓
TOTP
Duo provides TOTP (Time-based One-Time Password) as an authentication factor by generating a temporary six-digit code based on RFC 6238, which the user enters during the AnyConnect VPN login process. Push notification is another Duo factor, where a request is sent to the user's registered mobile device, and the user approves or denies the login attempt via the Duo Mobile app. Both factors satisfy the requirement for multi-factor authentication by adding a second layer beyond the primary password.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between authentication factors (like TOTP and push) and authentication protocols (like RADIUS and LDAP), leading candidates to mistakenly select protocols as factors.
Detailed technical explanation
How to think about this question
Duo's TOTP implementation uses a shared secret key and the current time to generate a one-time password that is valid for a short window (typically 30 seconds), ensuring replay resistance. Push notifications leverage Duo's proprietary protocol over HTTPS to deliver a real-time prompt to the Duo Mobile app, which uses a device-specific key to cryptographically sign the approval response. In a Cisco AnyConnect deployment, Duo integrates via the RADIUS protocol or the Duo Authentication Proxy, where the VPN headend sends authentication requests to Duo, which then challenges the user for the second factor.
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 junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
