  1. Dual-factor authentication

  2. Multifactor authentication

  3. Single factor authentication

  4. Biometric authentication

Answer: C Explanation:

Multi-factor authentication (MFA) is a method of computer access control which a user can pass by successfully presenting authentication factors from at least two of the three categories:

knowledge factors (quot;things only the user knowsquot;), such as passwords possession factors (quot;things only the user hasquot;), such as ATM cards inherence factors (quot;things only the user isquot;), such as biometrics

In this question a username, password, and a four-digit security pin knowledge are all knowledge factors (something the user knows). Therefore, this is single-factor authentication.

  1. Mandatory access control

  2. Discretionary access control

  3. Rule based access control

  4. Role based access control

Public Sensitive Private Confidential

In this case the file is marked confidential, and the user does not have that clearance level and cannot access the file.
