Which of the following ensures data is unrecoverable on a lost or stolen mobile device?

Answer options

• A. Device encryption
• B. Remote wipe
• C. Data backup

Correct answer: B

Explanation

The correct answer is B, Remote wipe, as it allows for the complete erasure of data on a device remotely, making it unrecoverable. Device encryption (A) secures data but does not erase it, Data backup (C) preserves information, and Fingerprint reader (D) is an authentication method, none of which ensure data is permanently erased.
