Motorola Solutions Deploy WLAN Solutions Sample Questions:

1. You have deployed and configured an AP7131 dual radio to operate with 40 MHz channels in the UNII-2 band. You have also configured the AP to use WPA2-CCMP encryption with PSK authentication. To make sure that you have configured the security options correctly you capture traffic using a protocol analyzer. When you view the individual frames you notice that most of them are completely readable in a plain text form, and even the ones that appear to be encrypted show a great deal of plain text information when the frame is opened and viewed in the protocol analyzer. Which of the following best explains this situation?

A) Encryption has been misconfigured
B) Only Data MSDUs are encrypted
C) Management MPDUs are only partially encrypted
D) Only Control MPDUs are encrypted
E) The UNII-2 band is never encrypted since it is unlicensed

2. After setting up the WLAN according to the site survey, you observe unanticipated RF interference which can be neither eliminated nor avoided. In this situation what could be done to mitigate the effect on throughput?

A) Adjust fragmentation to require smaller frames
B) Eliminate all security mechanisms
C) Change the network type to an IBSS
D) Adjust fragmentation to require larger frames

3. You just received a call from a WLAN customer who explained that he is having problems downloading files and streaming video. In diagnosing and troubleshooting this issue, which of the following would be the BEST action to take?

A) Perform a non-associative site survey and analyze RF energy levels.
B) Perform a spectrum analysis to review data packets and interfering frequencies.
C) Perform a passive site survey and analyze RF energy levels.
D) Perform an active site survey and analyze continuous data streams.

4. You just received a call from a new client for which you recently installed a 2.4 GHz WiNG 5 WLAN. Employees are having no issues in most areas of the hospital. However, when they roam from one area to another on the second floor they regularly lose their connection. You visit the site to investigate and determine that microwave interference and the AP power settings are not contributing factors. Given the relevant facts of this situation, which of the following is the MOST likely cause?

A) APs in the problem area have not been configured with the 2.4 GHz non overlapping channels (1, 6, and 11)
B) A cell phone tower is directly behind the hospital
C) A WiMax tower is close by (250 meters)
D) Fresnel zone has not been properly tested and configured.
E) APs in the problem area have not been configured with the 5.0 GHz non overlapping channels (1, 6, and 11)

5. Motorola Thin APs can be ordered with integrated or external antennas. Which of the following scenarios would best be addressed with external antenna AP models?

A) APs will be mounted below the ceiling tiles and provide semi-directional coverage.
B) APs will be placed in common areas where cost and convenience are of greater concern than coverage.
C) APs will be mounted above the ceiling tiles and provide semi-directional coverage.
D) APs will be mounted to walls and provide semi-directional coverage
E) APs will be mounted in areas where aesthetics are of greater concern than coverage.
