CompTIA A+ Core 2 (220-1102) — Question 615

Which of the following is also known as something you know, something you have, and something you are?

Answer options

• A. ACL
• B. MFA
• C. SMS
• D. NFC

Correct answer: B

Explanation

The correct answer is B, MFA (Multi-Factor Authentication), as it encompasses three types of authentication: something you know (password), something you have (token), and something you are (biometric data). The other options do not represent these three categories; ACL (Access Control List) relates to permissions, SMS (Short Message Service) is a messaging service, and NFC (Near Field Communication) is a technology for wireless data transfer.
