A network engineer must segregate all IPads on the guest WLAN to a separate VLAN.

To segregate all iPads on the guest WLAN to a separate VLAN without using Cisco ISE, the engineer can create a local policy on the WLC (option A). This local policy can be configured to identify iPad devices and assign them to a specific VLAN based on their device profile or other identifying characteristics. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, especially the sections that cover local policies and device profiling on the WLC.
