What impact does TACACS+ have regarding console port access?

Local database is the sole authentication method

Authentication is managed through the TACACS+ server

TACACS+ (Terminal Access Controller Access-Control System Plus) is a protocol that provides centralized authentication, authorization, and accounting services for users who access network devices. When it comes to console port access on network devices, TACACS+ plays a critical role in managing user authentication.

The correct choice indicates that authentication for console access is handled by the TACACS+ server. This centralizes the management of user credentials and access permissions, allowing administrators to have a unified approach to securing access across multiple devices. By using TACACS+, all authentication requests made when accessing the console port are sent to the TACACS+ server, which authenticates the user based on the credentials stored in its database. This enhances security compared to local authentication, allowing administrators to enforce policies and maintain control over user access.

Other choices describe aspects that do not fully reflect the capabilities of TACACS+ in the context of console access. For instance, stating that the local database is the sole authentication method contradicts the essence of TACACS+, which is designed to centralize and enhance authentication methods. Additionally, the statement about level 15 users implies a limitation that could restrict user access without acknowledging the flexibility provided by TACACS+. Finally, asserting that TACACS+ disables all other authentication methods overlooks
