CompTIA A+ Core 2 (220-1002) — Question 20

Which of the following provide the MOST security for PCs and mobile devices? (Choose two.)

Answer options

• A. Access control lists
• B. Multifactor authentication
• C. Organizational unit
• D. Trusted software sources
• E. Data loss prevention
• F. Pre-shared key

Correct answer: B, D

Explanation

Multifactor authentication (B) adds an additional layer of security by requiring more than one form of verification, making unauthorized access significantly harder. Trusted software sources (D) ensure that the applications installed on devices are safe and legitimate, protecting against malware and other threats. The other options, while important, do not provide the same level of comprehensive security as the correct answers.
