Which two protocols can be used for AAA server communication? (Choose two.)
- TACACS+
- Kerberos
- RADIUS
- LDAP
- SSH
Explanation: According to the sources, AAA stands for Authentication, Authorization, and Accounting, and these services can be implemented using either a local database on individual devices or a centralized AAA server for improved scalability. In centralized environments, the two primary protocols used for communication between network devices and the AAA server are TACACS+ and RADIUS. While TACACS+ is a Cisco proprietary protocol, RADIUS is an IETF standard. Centralized management platforms, such as Cisco ISE, support both protocols to provide an authoritative source for identity management and security policy enforcement across the enterprise.
