B. an RF planning tool will measure the RF coverage by AP locations, indicating antennas and output power
C. an RF planning tool does a better job of showing actual -65 dBm edges
D. an RF planning tool is a predictive tool, where a site survey tool measures the actual RF environment
Answer: D

9. Which method can be used by the Cisco Wireless LAN Controller system to determine
whether there is a rogue AP or not?
A. observation of unencrypted traffic that should be encrypted for an SSID that it owns
B. detection of an organizationally unique identifier not assigned to Cisco devices
