Which two methods can the AP use to locate a wireless controller?

Lightweight access points are being deployed in remote locations where others are already operational. The new access points are in a separate IP subnet from the wireless controller. OTAP has not been enabled at any locations. Which two methods can the AP use to locate a wireless controller? (Choose two.)

A.
NV-RAM IP address

B.
master

C.
primary, secondary, tertiary

D.
DHCP

E.
local subnet broadcast

F.
DNS

Over-the-Air-Provisioning (OTAP) Process
During the LAP boot process, the LAP uses different mechanisms in order to discover controllers that it can join. The LAP keeps each of the controller that IP addresses it learned through the different methods in different lists in order to reflect how the LAP learned about them. For example, the LAP can learn management IP addresses of multiple controllers through the DNS entry for CISCO-LWAPP-CONTROLLER.localdomain, DHCP option 43, through broadcasts on the local subnet, locally stored controller IP address discovery, and through OTAP. Once the access point has completed the LWAPP WLC Discovery steps, it chooses a WLC from the candidate WLC list and sends that WLC an LWAPP Join Request.
