Refer to the exhibit. A network administrator must implement device access controls on a Cisco Catalyst C9800-80 WLC to secure administrative access for the GUI and CLI using TACACS+. The administrator is configuring the WLC directly using NETCONF with a Python script to define a TACACS+ server. This server will handle authentication for GUI and CLI access. The TACACS+ server at 192.168.1.100 requires a specific setting to ensure it is the primary server for authentication requests from the WLC. The administrator confirmed that the shared secret Cisco123 matches the server configuration, and the timeout is set to 10 seconds. Which XML code snippet must be placed onto the box in the code to complete the script?
