CompTIA Network+ N10-009 Practice Question

The correct answer is 'Biometric verification', such as fingerprint or facial recognition, because it adds a layer of security that is difficult to replicate or steal, compared to knowledge or possession factors. 'Using a security question' often involves easily discoverable or guessable information, thus it is less secure. 'Requiring a company ID badge' primarily secures physical access but does not typically integrate directly into digital authentication systems for cloud services. 'Exclusively using a complex password' does not constitute MFA, as it does not involve multiple distinct categories of credentials.
