Which A record type should be configured for access points to resolve the IP address of a wireless LAN controller using DNS?

The name `CISCO.CONTROLLER.localdomain` is not the standard or recognized A record name used by CAPWAP APs for WLC discovery via DNS.

While including 'CAPWAP' is correct, using dots instead of hyphens (`CISCO.CAPWAP.CONTROLLER.localdomain`) does not match the required naming convention for AP discovery via DNS.

The name `CISCO-CONTROLLER.localdomain` is incomplete as it omits 'CAPWAP', which is a crucial part of the standardized DNS record name for CAPWAP AP discovery.

For Cisco CAPWAP-based access points to resolve the IP address of a wireless LAN controller using DNS, a specific A record named `cisco-capwap-controller.localdomain` (where .localdomain is replaced by the actual local domain name) must be configured in the DNS server. This standardized naming convention allows the APs to successfully find their controller.
