The correct answer is to configure secondary authentication via Duo after Azure AD, because this architecture preserves Azure AD as the primary identity provider while Duo adds an extra MFA layer through a custom control or conditional access policy. Technically, Duo’s Azure AD integration intercepts the authentication flow after the user has already validated against Azure AD, then enforces a Duo push, phone call, or passcode challenge before granting access to cloud applications. On the Cisco SCOR 350-701 exam, this scenario tests your understanding of multi-factor authentication integration in hybrid identity environments—a common trap is assuming Duo replaces Azure AD as the IdP, when in fact it supplements it. Remember the memory tip: “Primary stays, secondary plays”—Azure AD handles the first factor, Duo handles the second.

This 350-701 practice question tests your understanding of cloud security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
A company wants to use Cisco DUO for MFA to protect access to its Azure AD applications. Which authentication method should be configured for cloud applications?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Secondary authentication via DUO after Azure AD
When integrating Cisco DUO with Azure AD for MFA, the recommended approach is to configure DUO as a secondary authentication provider after Azure AD handles primary authentication. This is achieved by using DUO's Azure AD integration, which acts as a custom control or a conditional access policy that triggers DUO MFA after the user has already authenticated against Azure AD. This ensures that Azure AD remains the identity provider (IdP) for primary authentication, while DUO provides an additional layer of security via a secondary push, phone call, or passcode.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Secondary authentication via DUO after Azure AD
Why this is correct
DUO provides MFA as a second factor after Azure AD validates the user identity.

✗
DUO for RADIUS authentication
Why it's wrong here
RADIUS is for VPN or network device authentication, not cloud applications.
✗
DUO as a SAML identity provider
Why it's wrong here
Used for on-prem applications that support SAML, not cloud SaaS.
✗
Primary authentication via DUO
Why it's wrong here
DUO is not designed as a primary IdP for cloud applications.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that DUO can serve as a primary identity provider for cloud applications, but the trap here is that DUO is strictly a secondary authentication factor and must be layered after the primary IdP (Azure AD) to protect existing cloud applications without breaking the authentication chain.
Detailed technical explanation
How to think about this question
Under the hood, the DUO Azure AD integration leverages the 'DUO Security' enterprise application in the Azure AD gallery, which uses a custom SAML or OIDC flow where Azure AD authenticates the user first, then redirects to DUO for MFA via a conditional access policy. A subtle behavior is that DUO's 'Secondary Authentication' mode requires the user to have a valid Azure AD session before DUO prompts, which prevents MFA fatigue attacks by ensuring the user is already verified by Azure AD. In a real-world scenario, if an organization uses Azure AD P2 with Conditional Access, they can configure DUO as a 'Grant' control to require MFA via DUO for specific cloud apps, ensuring seamless integration without changing the primary authentication flow.

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.
