Which description is correct with regard to the operation of an access point in Rogue Location discovery Protocol Mode?

  1. The AP uses the existing wireless infrastructure in order to scan for rogue AP#39;s. Once discovered, these rogues are added to a local list that includes the rogue#39;s BSSIDs, MAC addresses and any discovered security provisions (WPA, WEP etc)

  2. The AP moves to the rogue channel and attempts to connect to the rogue as a client. The AP then tries to obtain an IP address and forwards a UDP packet to the controller through the rogue. If the controller receives this packet, the network administrator is notified that a rogue AP has been discovered on the wired network

  3. The AP detects a rogue client and then the network administrator is able to contain both the rogue AP and the rogue clients. This can be achieved because 802.11 deauthentication packets are sent to clients that are associated to rogue APs so threats such as holes are mitigated

  4. The AP determines whether or not a rogue access point is on a trusted network. It does not provide RF service of any kind but rather receives periodic rogue access point reports from the controller and sniffs all ARP packets. If it finds a match between an ARP request and a MAC address it receives from the controller. It generates a rogue access point alert

to the controller

Answer: B
