Answer. is correct. Both Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP) use Point-to-Point Protocol (PPP).

Diameter is an authentication service, but biometrics is an authentication method.

Kerberos is an authentication service, but it doesn’t use PPP and Lightweight Directory Access Protocol (LDAP) as a method of querying directories.

Security Assertion Markup Language (SAML) is an Extensible Markup Language (XML)–based data format used for single sign-on.

Objective: 5.2 Given a scenario, select the appropriate authentication, authorization or access control.
