220-1002 Question #663: Real Exam Question with Answer & Explanation
The correct answer is C: PIN. Adding a PIN satisfies the multifactor authentication requirement by introducing an additional device-bound verification step that is distinct from the reusable username and password credentials.
Question
A technician is implementing multifactor authentication for logins to the network. The network already requires a username and password to authenticate users. Which of the following should the technician add to meet the multifactor requirement?
Options
- APassphrase
- BKnowledge-based authentication
- CPIN
- DThumbprint
Explanation
Adding a PIN satisfies the multifactor authentication requirement by introducing an additional device-bound verification step that is distinct from the reusable username and password credentials.
Common mistakes.
- A. A passphrase is a variation of a password and falls under the 'something you know' category, the same factor type as the existing password, so it does not introduce a new authentication factor.
- B. Knowledge-based authentication relies on security questions, which are also classified as 'something you know' and therefore do not add a distinct factor beyond the existing username and password.
- D. A thumbprint is a biometric 'something you are' factor that is valid for MFA but typically requires dedicated fingerprint reader hardware at each network login point, making it less practical than a device-bound PIN for this network authentication scenario.
