What is a feature of TACACS+ compared to its predecessor TACACS?

1. It is backwards compatible

2. It was released as an open source project

3. It supports more authentication requests

4. It was designed for simpler implementations

The correct answer is: It supports more authentication requests

The feature of TACACS+ that distinguishes it from its predecessor TACACS is its ability to support more authentication requests. TACACS+ enhances the functionality of TACACS by introducing a more sophisticated protocol that provides greater flexibility in handling authentication. This is accomplished through its ability to support multiple types of authentication, authorization, and accounting requests in a single connection, which improves efficiency and usability in network authentication scenarios. TACACS+ also allows for separate handling of authentication, authorization, and accounting, which can streamline processes and provide a more granular control over user permissions and access rights. The design of TACACS+ enables organizations to implement complex authentication scenarios more effectively than the earlier TACACS could manage. Therefore, the increased capacity for handling authentication requests is a key advancement in TACACS+ relative to its predecessor.
