A senior administrator has been directed to incorporate AAA services within a domain environment for regulatory compliance purposes. Which of the following standards will enable the use of an AAA server in a domain environment?
Correct Answer: B
Explanation
802.1X is a standard that enables the use of an AAA server in a domain environment by providing port-based network access control. 802.1X authenticates users or devices before granting them access to the network resources, and can also authorize them based on their roles or policies. 802.1X can work with different AAA protocols, such as RADIUS or TACACS+, to communicate with the AAA server.
