Exam 300-715 topic 1 question 141 discussion

I go for C and E A Cisco ISE administrator can manage device administration using TACACS Plus (TACACS+). Note You should check the Enable Device Admin Service check box in the Administration > System > Deployment > General Settings page to enable TACACS+ operations. Ensure that this option is enabled in each PSN in a deployment. Note Cisco ISE requires a Device Administration license to use the TACACS+ service on top of an existing Base or Mobility license. The Device Administration license is a perpetual license. If you are upgrading from an earlier release to Cisco ISE Release 2.0 and later, and want to enable the TACACS+ service, you must order the Device Administration license as a separate add-on license. The number of Device Administration licenses must be equal to the number of device administration nodes in a deployment. https://www.cisco.com/c/en/us/td/docs/security/ise/2-4/admin_guide/b_ISE_admin_guide_24/m_ise_tacacs_device_admin.html

The correct answers are Device Administration License and Device Admin Service. The Device Administration License is required to enable the TACACS+ feature in Cisco ISE. The Device Admin Service is a component of the Device Administration License that provides centralized authentication, authorization, and accounting (AAA) for network devices.

To enable the TACACS+ feature on Cisco ISE, the two features that must be used are: E. Device Admin Service: This service must be enabled to support the TACACS+ feature on Cisco ISE. The Device Admin Service provides centralized authentication, authorization, and accounting (AAA) for network devices and users, and is used for device administration tasks such as device management and configuration. C. Device Administration License: This license is required to use the Device Admin Service on Cisco ISE. The license provides access to the Device Administration functionality within Cisco ISE, including TACACS+ authentication, authorization, and accounting (AAA) services.
