Question

The company requires all users to authenticate to the network with a smart card, a pin number, and a fingerprint scan. Which of the following BEST describes the user authentication being used?

Since all three categories are present, this is MFA - not simply two-factor authentication (2FA), which would require exactly two. Biometrics describes only the fingerprint component, and single sign-on (SSO) refers to using one set of credentials to access multiple systems, which is unrelated here.
