CompTIA Security+ (SY0-701) — Question 142

A network manager wants to protect the company's VPN by implementing multifactor authentication that uses:

Something you know -

Something you have -

Something you are -
Which of the following would accomplish the manager's goal?

Answer options

• A. Domain name, PKI, GeoIP lookup
• B. VPN IP address, company ID, facial structure
• C. Password, authentication token, thumbprint
• D. Company URL, TLS certificate, home address

Correct answer: C

Explanation

The correct answer is C because it includes a password (something you know), an authentication token (something you have), and a thumbprint (something you are), which aligns perfectly with the multifactor authentication requirements. Options A, B, and D do not provide the necessary combinations of knowledge, possession, and biometric factors needed for effective multifactor authentication.
