The correct answer is A. TACACS+.
AAA stands for Authentication, Authorization, and Accounting. It is a framework that is used to control access to network resources, ensure security, and monitor usage. There are several protocols that can be used to implement AAA, including TACACS+, RADIUS, LDAP, and local authentication.
TACACS+ (Terminal Access Controller Access-Control System Plus) is a Cisco-developed protocol that separates the AAA functions, which provides greater flexibility and control. It provides separate authentication, authorization, and accounting services, allowing for fine-grained control over who can access network resources and what they can do with them.
Single sign-on (SSO) is a method of authentication that allows a user to log in to multiple applications and systems with a single set of credentials. It is not used for accessing a network switch.
LDAP (Lightweight Directory Access Protocol) is a protocol that provides a mechanism for accessing and managing distributed directory information services over an IP network. While it can be used for authentication, it is not typically used in conjunction with standard AAA configurations for network switches.
Local authentication is a method of authentication where the username and password are stored locally on the device being accessed. This method is not typically used in large networks as it does not provide centralized control and management of authentication.
In summary, a network administrator can use TACACS+ to access a network switch using standard AAA configurations.
