220-1102 Question #41: Real Exam Question with Answer & Explanation

Question

A user enabled a mobile device's screen lock function with pattern unlock. The user is concerned someone could access the mobile device by repeatedly attempting random patterns to unlock the device. Which of the following features BEST addresses the user's concern?

Options

• ARemote wipe
• BAnti-maIware
• CDevice encryption
• DFailed login restrictions

Explanation

To address the concern of unauthorized access through repeated pattern unlock attempts on a mobile device, failed login restrictions are the most effective feature.

Approach. Failed login restrictions, often combined with a temporary lockout mechanism or data erasure after a certain number of incorrect attempts, directly address the concern of someone repeatedly attempting to guess the unlock pattern. This feature will either lock the device for a period or wipe its data after too many incorrect attempts, making brute-forcing the pattern impractical and securing the device.

Common mistakes.

• A. Remote wipe allows an administrator to erase all data on a lost or stolen device but does not prevent someone from repeatedly attempting to guess an unlock pattern in the first place.
• B. Anti-malware software detects and removes malicious software but is unrelated to preventing brute-force attempts on a screen unlock pattern.
• C. Device encryption protects data at rest if the device is lost or stolen, but it does not prevent or deter repeated attempts to unlock the active screen lock.
