Why is an AP joining a different WLC than the one specified through option 43?

A. The WLC is running a different software version
B. The API is joining a primed WLC
C. The AP multicast traffic unable to reach the WLC through Layer 3
D. The APs broadcast traffic is unable to reach the WLC through Layer 2

Correct Answer: B

The order of selecting a WLC according to the exam guide:

1. If the AP has previously joined a controller and has been configured or "primed" with a primary, secondary, and tertiary controller, it tries to join those controllers in succession.
2. If the AP does not know of any candidate controller, it tries to discover one (which includes the use of option 43).
