Given: ABC Company is interested in deploying an IEEE 802.11 network that supports wVoIP devices. During a proof-of-concept test, they deployed a WLAN controller, one lightweight AP, and QoS features in support of their voice and data client devices in the 2.4 GHz band. The network administrator has configured the access point to perform client connectivity and rogue wireless device scanning. As a test, John places a rogue AP on his network and configures it to use channel 11. The WLAN controller never reports the rogue AP.

Why does the WLAN controller never report the rogue AP?

A.
Lightweight APs can only scan for rogue devices on the channel they are using. The authorized AP is on channel 1.

B.
Admission Control is enabled on the WLAN controller, and the voice client is actively communicating through the AP during the entire test.

C.
The rogue AP is using the encrypted management frame feature which masks its presence.

D.
The rogue AP is operating in APSD mode, and therefore does not transmit identifying management frames.
