How can an access point discover a wireless LAN controller? (Choose two.)

Access points can discover a Wireless LAN Controller (WLC) through several methods. DHCP Option 43 is a common and efficient method where a DHCP server provides the WLC's IP address to the AP during its IP address lease process. This allows the AP to directly contact the WLC. Broadcasting on the local subnet is another discovery method; the AP sends out a broadcast message (often a CAPWAP discovery request) on its local network segment, and any WLC on that segment will respond. Cisco Discovery Protocol (CDP) neighbor discovery is used for device information exchange between directly connected Cisco devices, but not typically for WLC discovery by an AP. Querying other APs is not a standard or reliable WLC discovery mechanism. DNS lookup for CISCO-DNA-PRIMARY.localdomain is not a standard WLC discovery method; DNS is used for resolving hostnames to IP addresses, and while a specific DNS entry could be configured, this exact format is not a default discovery mechanism.
