View Answer

Answer: D

Explanation:

A. Remote wipe – While this is a valuable security feature for a lost or stolen device, it’s not the best response to the concern of someone attempting random patterns to unlock the device.

B. Anti-malware – Anti-malware software is crucial for protecting a device from malicious software, but it doesn’t directly address the concern of someone physically attempting to unlock the device through random patterns.

C. Device encryption – Encryption is a powerful security tool that protects data stored on the device, but it doesn’t prevent someone from attempting to unlock the device via the screen lock function.

D. Failed login restrictions – This is the feature that directly addresses the user’s concern. With failed login restrictions, the device can be set to require a longer delay between unlock attempts after a certain number of failed attempts, or even to wipe the device after a set number of failed attempts. This makes a brute force attack (i.e., trying every possible combination) infeasible.

Therefore, to address the user’s concern about someone accessing the mobile device by repeatedly attempting random patterns, the best feature to implement would be failed login restrictions.
