CompTIA A+ Core 2 (220-1102) — Question 560

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

Answer options

• A. Remote wipe
• B. Biometrics
• C. Personal identification number
• D. Log-in attempt restrictions

Correct answer: B

Explanation

Biometrics is the most secure option because it uses unique physical traits of the user, such as fingerprints or facial recognition, making it very difficult for unauthorized individuals to gain access. In contrast, remote wipe, personal identification numbers, and login attempt restrictions provide varying levels of security but can be bypassed or compromised more easily.
