CompTIA Security+ - Device Authentication Example Questions

Test your knowledge of Device Authentication

Question 1

A new employee received an email asking to install a mobile device management app on his personal tablet. What should he do before proceeding?

Correct Answer: Verify the request with the IT department

To avoid potential security risks, the employee should verify the request with the IT department to ensure it's legitimate. Other options might lead to installing unauthorized or even malicious software.

Question 2

A company needs to improve security for smartphones accessing the corporate network. Which device authentication method should they implement?

Correct Answer: Multi-factor authentication

Multi-factor authentication provides better security as it combines more than one factor for authenticating access such as something the user knows (password), something the user has (token), or something the user is (biometrics). Other options are less secure as they rely on only one factor.

Question 3

A company's access control system was recently breached. They want to strengthen their device authentication. Which of the following should they implement?

Correct Answer: Certificate-based authentication

Certificate-based authentication provides a better security solution, as it uses digital certificates to validate the device's identity. Other options have lower levels of security or are more vulnerable to attacks.
