An organization secures its network with multi-factor authentication using an authenticator app on employee smartphone. How is the application secured in the case of a user’s smartphone being lost or stolen?
A.
The application requires an administrator password to reactivate after a configured Interval.
B.
The application requires the user to enter a PIN before it provides the second factor.
C.
The application challenges a user by requiring an administrator password to reactivate when the smartphone is rebooted.
D.
The application verifies that the user is in a specific location before it provides the second factor.
The application requires the user to enter a PIN before it provides the second factor.. Security fundamentals require distinguishing identity, authorization, accounting, encryption, inspection, and physical protection. Cisco CCNA 200-301 v1.1 includes this under Security Fundamentals, where the exam expects engineers to recognize the device behavior that actually produces the required outcome. The question is best solved by reading the operational clue rather than choosing a familiar acronym. The incorrect choices apply a security term in the wrong control category or protect a different part of the system. In a production network, the wrong choice would normally create an outage, leave a management or security gap, or send troubleshooting toward the wrong subsystem. The selected answer is the one that matches the control-plane, data-plane, wireless, security, services, or automation mechanism described in the question. That is why it remains the verified answer for this item.
