CompTIA A+ Core 2 (220-1202) — Question 9

A technician is deploying mobile devices and needs to prevent access to sensitive data if the devices are lost. Which of the following is the best way to prevent unauthorized access if the user is unaware that the phone is lost?

Answer options

Correct answer: A

Explanation

Encryption is the most effective method to secure sensitive data, as it ensures that even if the device is lost, the information remains inaccessible without the proper decryption key. While remote wipe can erase data, it requires the user to be aware that the device is lost. Geofencing can restrict access based on location, and facial recognition is a security measure that can be bypassed if the device is already in the hands of an unauthorized user.
