A network administrator is looking to implement a solution allowing users to utilize a common
password to access most network resources for an organization. Which of the following would
BEST provide this functionality?

A.
RADIUS

B.
Single sign on

C.
Multifactor authentication

D.
Two-factor authentication

Explanation:
Single sign-on (SSO)is a session/user authentication process that permits a user to
enter one name and password in order to access multiple applications. The process authenticates
the user for all the applications they have been given rights to and eliminates further prompts
when they switch applications during a particular session.
