Microsoft Azure Fundamentals AZ-900 Practice Question

Multi-factor authentication (MFA) provides the organization with additional layers of security because users must provide more than one form of verification, such as a password and a code sent to their phone. This reduces the risk if a password is compromised.

Single sign-on (SSO) simplifies access by allowing users to sign in once to access multiple resources but doesn't necessarily improve security in this scenario.

Passwordless authentication removes the need for passwords and uses methods like biometrics, which may not align with the scenario's requirement for adding verification on top of a password.

Role-based access control (RBAC) is an authorization system that defines access permissions based on roles; it does not directly address the need for additional authentication steps.
