CompTIA A+ Core 2 (220-1102) — Question 451

Which of the following describes a concept that requires using a combination of an ID, a password, and a biometric?

Answer options

• A. Types of security
• B. Access control
• C. Principle of least privilege
• D. Multifactor authentication

Correct answer: D

Explanation

The correct answer is D, as multifactor authentication specifically involves using multiple forms of verification, including something you know (password), something you have (ID), and something you are (biometric). Options A and B do not accurately describe this combination of factors, and C relates to limiting access rather than the method of authentication itself.
