A network administrator of a school district must implement a DNS-based ACL to block students from accessing certain teacher URLs where test papers are hosted. The infrastructure contains a Cisco Catalyst 9800 WLC with 25 9136 APs. The administrator configured the URL Filter List called urllist_flex_pre, applied the URL Filter List to the default Flex Profile, and defined Preauth called urllist_local_preauth and Postauth called urllist_local_postaut URL Filter List. Which configuration must the administrator apply to implement the ACL on the default policy profile?
