Which of the following are AP discovery methods to locate a WLC?

Access Points (APs) utilize specific methods to discover and connect to Wireless LAN Controllers (WLC). Among these methods, the locally stored IP address is one approach that an AP uses to locate a WLC if it has been previously configured with a specific IP address. This means that if the AP has this information saved, it can directly reach out to the WLC without needing to rely on dynamic discovery processes.

In addition to this method, DHCP Option 43 is a mechanism that allows a WLC's IP address to be provided during the DHCP lease process. If an AP is acquiring its IP address through DHCP, the server can include the WLC's IP address in the options it sends back, allowing the AP to discover and connect to the WLC based on this information.

Thus, both the locally stored IP address and the DHCP Option 43 are valid methods for AP discovery. This combination of options enables flexibility and ensures that APs can reliably locate and communicate with WLCs in a network, especially in scenarios where static or dynamic configurations are preferred. Other choices might refer to different networking protocols or methods that do not directly relate to this specific discovery process.
