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

A.
TACACS+

B.
Smartcards

C.
Biometrics

D.
Kerberos

Explanation:
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.
