Which authentication method supports multiple factors or methods and can be configured as part of the Citrix ADC authentication flow?

• A. Biometric authentication
• B. Certificate-based authentication
• C. SAML authentication
• D. NFactor authentication

Answer: (D)

NFactor authentication is Citrix ADC’s multi-factor authentication flow engine. It lets you define a sequence or tree of authentication prompts, combining different factors and methods within a single login flow. You can require a password and then add a second factor like an OTP, a certificate check, or a push notification, and tailor the steps based on user, group, device, or risk context. This flexibility is why it’s the method that supports multiple factors or methods and can be configured as part of the ADC authentication flow.

Biometric or certificate-based methods are typically single-factor on their own, even though they are strong factors. SAML is a federation protocol for SSO, not a multi-factor flow by itself.
