220-1102 Question #725: Real Exam Question with Answer & Explanation

Question

Which of the following is the most secure method to protect a mobile device from unwanted access?

Options

• ARemote wipe
• BBiometrics
• CPersonal identification number
• DLog-in attempt restrictions

Explanation

Biometrics offers the most secure method for protecting a mobile device from unwanted access because it uses unique physical characteristics that are difficult to replicate.

Common mistakes.

• A. Remote wipe is a recovery feature used to erase data after a device is lost or stolen, not a primary method to prevent unwanted access in the first place.
• C. A Personal Identification Number (PIN) can be guessed or observed, making it less secure than biometric authentication, which relies on unique physical attributes.
• D. Log-in attempt restrictions are a deterrent measure, but they don't prevent the initial unauthorized access attempt itself and can be bypassed if the correct credential is eventually guessed.
