Which of the following is a protocol that centralized authentication, authorization, and accounting quizlet?

Which of the following protocols is used by PPP?

PPP operates using different network layer protocols (e.g., IPX and AppleTalk), whereas SLIP uses only TCP/IP-based IP. PPP and SLIP will encapsulate a datagram and other network layer protocol information over point-to-point links. These are called NCPs.

What does AAA stand for quizlet?

Authentication, Authorization and Accounting.

Which server can act as a centralized authentication server in your network quizlet?

Client server: allows you to have a centralized database of users so that authentication is provided in one place. You need a topology that is scalable to use in your network.

Which of the following authentication protocols transmits passwords in cleartext?

What function does the TACACS+ protocol perform quizlet?

The RADIUS protocol encrypts the entire packet transmission. The TACACS+ protocol allows for separation of authentication from authorization.
