Which of the following is a dynamic discovery method an AP can use?

The dynamic discovery method that an Access Point (AP) can utilize is DHCP option 43. This method allows an AP to discover the address of a controller dynamically through a DHCP server. When a client device requests an IP address from the DHCP server, the server can provide additional configuration settings, including option 43, which contains the IP address of the controller that the AP should connect to. This setup enables the AP to automatically find and communicate with the controller without requiring manual configurations.

Dynamic discovery methods are particularly useful in large-scale deployments, where manually configuring each AP would be impractical. By relying on DHCP option 43, network administrators can streamline the deployment process and ensure that APs dynamically connect to the network with minimal manual intervention. This flexibility is important in maintaining a robust and easily scalable wireless network.

Other methods like static IP configuration, direct server configuration, and manual MAC address entry do not fall under dynamic discovery. Static IP requires each device to be configured with a specific address manually; direct server configuration involves individual setup on each device; and manual MAC address entry involves explicitly entering ethernet addresses, which is not dynamic in nature.
