Which one of the following makes a controller failure most disruptive to connected clients?
- A . The controller must take time to find a replacement for itself.
- B . The clients must take time to find a new controller to join.
- C . The APs must take time to find a new controller to join.
- D . The clients must wait for the Spanning Tree Protocol to unblock the links from the APs to the new controller.
To which CMX port does a WLC send AoA messages?
- A . A WLC does not send AoA messages; APs send them directly to CMX.
- B . TCP 16113

A wireless associate claims to have measured a 25 dB attenuation behind a concrete wall and asserts that the common reference table indicates 12 dB is wrong.
What can you tell the associate?
- A . The associate may have measured the attenuation from the middle of the room instead of right behind the wall, thus leading to the discrepancy.
- B . The table is only indicative. Local differences may be found, and this is why surveys are important.
- C . The table is old. Newer walls have metal reinforcement that increases the attenuation.
- D . The table indicates the one-way attenuation, but Wi-Fi communication is bidirectional, so 24 to 25 dB is correct.
Why are Wi-Fi-based indoor location services important?
- A . For tracking mobile devices
- B . For facilitating troubleshooting (such as when a connection fails as a device entered the elevator)
- C . For optimizing associated technical resources (such as adding more APs in an area)
- D . For pushing sales campaigns or promotions to in-store visitors
- E . For accessing personal data on mobile devices
- F . For promoting real estate pricing for shopping centers by sharing the footfall details of the most visited area
- G . For pushing applications to the mobile devices
Which of the following is an authentication framework most likely to be found in Enterprise WLANs?

Which two of the following statements are true about NDP messages?
- A . NDP messages are sent only on an AP’s operating channel.

- C . NDP messages are transmitted using the AP’s normal transmit power level.
- D . NDP messages are transmitted using the AP’s maximum supported transmit power level.
