A security administrator must use a password and a token to log in to the server. Which of the following processes does this describe?

Kerberos is a ticket-based network authentication protocol designed for single sign-on, not a process that inherently combines a password with a physical token.

RADIUS is a centralized AAA networking protocol that can carry credentials but is not itself the name of the process of using a password plus token.

Biometric authentication uses physical characteristics such as fingerprints or iris scans, which are not described in this scenario.

Multifactor authentication (MFA) requires two or more authentication factors from separate categories. A password is a knowledge factor (something you know) and a token is a possession factor (something you have), satisfying the core MFA requirement. This combination ensures that compromising one factor alone is insufficient to gain access.

LDAP is a directory service access protocol used to query and manage user records, not an authentication process combining a password and token.
