CCNA: Cisco Certified Network Associate — Question 318

An organization secures its network with multi-factor authentication using an authenticator app on employee smartphones. How is the application secured in the case of a user's smartphone being lost or stolen?

Answer options

• A. The application requires the user to enter a PIN before it provides the second factor
• B. The application requires an administrator password to reactivate after a configured interval
• C. The application verifies that the user is in a specific location before it provides the second factor
• D. The application challenges a user by requiring an administrator password to reactivate when the smartphone is rebooted

Correct answer: A

Explanation

The correct answer is A because requiring a PIN adds an extra layer of security, making it more difficult for unauthorized users to access the second factor. Options B and D involve administrator passwords, which may not effectively secure the app in a lost or stolen scenario, while option C relies on location, which could be circumvented.
