A network administrator is troubleshooting a problem with HP MSM APs that fail to become
controlled by the HP MSM Controller. The APs are deployed across a layer 3 boundary from the
controller, and their DHCP server provides them with the controller’s address.
The network administrator observes the following behavior in the controller’s web browser
interface:
The APs appear in the Discovered APs section.
The APs status remains Pending, and the Diagnosis reads Waiting acceptance.
The APs never progress to a different status.
What might be the problem?

A.
The controller enforces AP authentication, and the APs have not been authorized.

B.
The controller does not have a route to the APs subnet.

C.
The APs are running a different software version from the controller.

D.
The controller does not permit device discovery on the interface on which APs contact it.

E.
The DHCP option have been misconfigured.
