A network engineer is implementing BYOD on a wireless network.

 For a BYOD setup using a dual SSID approach, the first SSID is typically used for device registration and the second for network access. Setting the NAC State to Radius NAC enables the network access control (NAC) to use RADIUS for authentication, authorization, and accounting. Allowing AAA Override enables the RADIUS server to dynamically change the VLAN and ACLs assigned to the endpoint, which is crucial for BYOD where devices need to be placed into the correct VLAN based on user role and device type. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, particularly the chapters on BYOD and advanced WLAN configuration.
