CompTIA ITF+ (FC0-U61) — Question 79

A user logs into a laptop using a username and complex password. This is an example of:

Answer options

• A. biometrics
• B. multifactor authentication
• C. least privilege
• D. single-factor authentication

Correct answer: D

Explanation

The correct answer is D, as the user is using only one method of authentication (the password) to gain access, which classifies it as single-factor authentication. Options A and B are incorrect because biometrics and multifactor authentication involve additional forms of verification beyond just a username and password. Option C is not applicable here since least privilege refers to the principle of restricting user access rights to the bare minimum necessary.
