Which two features must be used on Cisco ISE to enable the TACACS+ feature? (Choose two.)

A Device Administration License is required in Cisco ISE to unlock and use the TACACS+ functionality for authenticating and authorizing administrative access to network devices. Without this license, TACACS+ features are not available.

Server Sequence is used to define the order in which identity sources are consulted, but it's a general configuration for authentication/authorization, not a feature that enables TACACS+ itself.

Command Sets are used for granular authorization of commands after TACACS+ is enabled and configured, not for enabling the TACACS+ feature itself.

The Device Admin Service must be enabled on the Policy Service Nodes in Cisco ISE to handle TACACS+ requests from network devices. This service processes the authentication and authorization policies specifically for device administration.

External TACACS Servers are external identity sources, not a feature on Cisco ISE that enables its own TACACS+ functionality; Cisco ISE acts as the TACACS+ server.
