A. B. C. D.D.
The correct answer is D. Single-factor authentication.
Authentication is the process of verifying the identity of a user or system. In this scenario, the user is logging into a laptop using a username and a complex password, which is an example of single-factor authentication.
Single-factor authentication requires only one form of identification, in this case, the password. While a complex password can increase the security of the authentication process, it is still considered a single-factor because it relies solely on something the user knows (the password) to authenticate them.
Biometrics (A) refers to the use of physical characteristics, such as fingerprints, iris scans, or facial recognition, for authentication.
Multifactor authentication (B) requires at least two forms of identification to authenticate a user, such as a password and a fingerprint scan.
Least privilege (C) is a security principle that restricts user access to only the resources necessary to perform their job functions, reducing the risk of unauthorized access or actions.
Therefore, the correct answer to this question is single-factor authentication (D), as it only requires one form of identification to authenticate a user, in this case, a complex password.
