CompTIA A+ Core 2 (220-1102) — Question 676

Which of the following ensures proprietary information on a lost or stolen mobile device cannot be accessed while the device is offline?

Answer options

• A. Remote wipe
• B. Mandatory screen locks
• C. Location applications
• D. Device data encryption

Correct answer: D

Explanation

Device data encryption protects the information stored on a mobile device by making it inaccessible without the correct decryption key, even if the device is offline. Remote wipe can erase data when the device is online but does not prevent access while offline. Mandatory screen locks offer some protection but can be bypassed if the device is stolen. Location applications help track the device's location but do not secure the data itself.
