Answer

C. Password and fingerprint scan

Explanation

MFA requires two or more authentication factors, such as something you know (password) and something you have (biometric scan).

Which of the following is an example of multi-factor authentication (MFA)? Learn how combining a password with a fingerprint scan meets MFA requirements and why this approach is critical for cybersecurity, as covered in the Cisco Certified Support Technician (CCST) Cybersecurity 100-160 exam.

The correct example of multi-factor authentication (MFA) is password and fingerprint scan.

  • MFA requires two or more authentication factors from different categories:
  • Something you know (knowledge): password, PIN, security question
  • Something you have (possession): smartphone, hardware token, smart card
  • Something you are (inherence): biometric data such as fingerprint, facial recognition, or iris scan.
  • Using a password (something you know) and a fingerprint scan (something you are) combines two different types of factors, which qualifies as MFA.
  • Other options, such as password and security question, use two knowledge factors and do not meet the MFA requirement, as true MFA must mix at least two categories.
  • MFA significantly increases account security because compromising one factor (like a password) does not grant access without the second, unrelated factor.

This combination uses both a knowledge factor and a biometric factor, fulfilling the requirements for multi-factor authentication and providing robust protection against unauthorized access.
