51.7% completeQuestionAn engineer configures an Authentication, Authorization, and Accounting (AAA) server to authenticate credentials for remote users. Credentials are forwarded to the AAA server from a firewall. Which AAA method does the engineer utilize?A.TACACS+B.RADIUSC.KerberosD.Active Directory
Solution
The engineer is utilizing either A. TACACS+ or B. RADIUS. Both of these are protocols used for AAA (Authentication, Authorization, and Accounting) services. They are used to forward credentials from a firewall or other network device to a central server for authentication.
However, without more specific information in the question, it's impossible to definitively say whether TACACS+ or RADIUS is being used. Both are commonly used for this purpose and operate in a similar manner.
Kerberos (C) and Active Directory (D) are also used for authentication, but they are not typically used to forward credentials from a firewall to a AAA server. Kerberos is a network authentication protocol that uses secret-key cryptography to authenticate client-server applications. Active Directory is a directory service developed by Microsoft for Windows domain networks and is included in most Windows Server operating systems.
