Multi-Factor Authentication (MFA) requires at least two different types of authentication factors:

Something you know (e.g., password or PIN)

Something you have (e.g., smartphone or hardware token)

Something you are (e.g., fingerprint or facial recognition)

Option A, sending a code to the user’s phone, is an example of " something you have " — a physical device that receives a one-time passcode. Combined with a password, this forms a proper MFA implementation.

B. Date of birth is another knowledge-based factor (like a password), not a second factor type.

C. Solving a math problem is not a recognized authentication factor.

D. A PIN is also " something you know " and does not count as a distinct MFA factor when paired with a password.

Authenticator apps, such as Google Authenticator or Microsoft Authenticator, can be configured to sendpush notificationsto users for approval when logging in. This is a form of multi-factor authentication.

FromAll-in-One Exam Guide:

“Push-based two-factor authentication uses an authenticator app to send a notification to a mobile device. The user must approve the login attempt in real time, ensuring the request is valid.”
