What are the interface statuses of a lightweight AP working in rogue-detection mode?
A. radios turned off, Ethernet interface up
B. radios and Ethernet interfaces up
C. radios turned on, Ethernetinterface shut down
D. radios turned on, Ethernet interface status controlled by Cisco WLC
Correct Answer: A
Explanation/Reference:
Explanation:
In this mode, the AP radio is turned off, and the AP listens to wired traffic only. The controller passes the APs configured as roguedetectors as well as lists of suspected rogue clients and AP MAC addresses. The rogue detector listens for ARP packets only, and can be connected to all broadcast domains through a trunk link if desired.

Poor wording, as always in Cisco questions. But the “Cisco answer” is A nevertheless:

this is shit. corret answer is B.
Rogue detector—An LAP dedicates itself to detecting rogue devices by correlating
MAC addresses heard on the wired network with those heard over the air. Rogue devices
are those that appear on both networks.
