CompTIA A+ Core 2 (220-1002) — Question 268

A technician is implementing multifactor authentication for logins to the network. The network already requires a username and password to authenticate users.
Which of the following should the technician add to meet the multifactor requirement?

Answer options

• A. Passphrase
• B. Knowledge-based authentication
• C. PIN
• D. Thumbprint

Correct answer: D

Explanation

The correct answer is D, Thumbprint, as it adds a biometric factor, which is necessary for multifactor authentication. Options A, B, and C all rely on knowledge-based factors (something the user knows), which do not satisfy the requirement for multifactor authentication as they do not introduce a second factor.
