Which of the following authentication methods is being referred to?

A.
Mutual

B.
Anonymous

C.
Multi-factor

D.
Biometrics

Explanation:
Multi-factor authentication involves a combination of multiple methods of
authentication. For example, an authentication method that uses
smart cards as well as usernames and passwords can be referred to as multi-factor authentication.
Answer option A is incorrect. Mutual authentication is a process in which a client process and server
are required to prove their identities to

each other before performing any application function. The client and server identities can be
verified through a trusted third party and use
shared secrets as in the case of Kerberos v5. The MS-CHAP v2 and EAP-TLS authentication methods
support mutual authentication.
Answer option B is incorrect. Anonymous authentication is an authentication method used for
Internet communication. It provides limited
access to specific public folders and directory information. It is supported by all clients and is used to
access unsecured content in public
folders. An administrator must create a user account in IIS to enable the user to connect
anonymously.
Answer option D is incorrect. Biometrics authentication uses physical characteristics, such as
fingerprints, scars, retinal patterns, and other
forms of biophysical qualities to identify a user.
