350-701 Practice Question: Use Cisco DUO for MFA to protect access to its…
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?
⚠ Common exam trap
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.

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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
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.
