CompTIA Security Plus Mock Test Q873

Which of the following services are used to support authentication services for several local devices from a central location without the use of tokens?

B. Smartcards
C. Biometrics
D. Kerberos

Correct Answer: A
Section: Access Control and Identity Management

ACACS allows a client to accept a username and password and send a query to a TACACS authentication server. It would determine whether to accept or deny the authentication
request and send a response back. The TIP would then allow access or not based upon the response, not tokens.

Incorrect Answers:
B: Smartcards are also known as identity tokens containing integrated circuits.
C: Biometrics is used for user authentication, not device authentication.
D: Kerberos uses tickets, which lists the privileges of that user, much like a token.
