CompTIA A+ Core 2 (220-1202) — Question 24

Which of the following is used in addition to a password to implement MFA?

Answer options

• A. Sending a code to the user's phone
• B. Verifying the user's date of birth
• C. Prompting the user to solve a simple math problem
• D. Requiring the user to enter a PIN

Correct answer: A

Explanation

Sending a code to the user's phone is a common method for MFA as it provides a second layer of security. The other options, such as verifying the user's date of birth or requiring a PIN, do not typically involve a separate communication method or real-time verification like the code sent to a phone does.
