Motorola Solutions Deploy WLAN Solutions Sample Questions:

1. You just installed a WiNG 5 RFS4O00 controller and several AP650s in a small branch office and clients on the wireless network cannot connect out to the internet. You have determined that the clients are associated and connected to the APs and you can ping the RFS4000 controller from your laptop. You connect to RFS4000 serially and start to troubleshoot the issue. Which of the following CLI commands can help you determine where the issue maybe occurring?

A) service pktcap on drop count 100
B) debug mstp protocol on rfs4000
C) show wireless interface packet blocks
D) show captive-portal client frames

2. An RFS controller has been deployed on the LAN of a large retail location. The sales floor, warehouse, and parking lot have been covered with overlapping coverage from 24 dual-
band 802.lln APs, which have been connected to existing Ethernet jacks throughout the facility. You begin testing the system using multiple 802.11n-capable workstations performing large, concurrent file transfers. Shortly after your tests begin, the wireless users begin complaining that their network access is extremely slow. Which of the following are possible reasons for this condition (select THREE)?

A) The wired network is using 100 Mbit rather than 1000 Mbit.
B) The wired network is flooding Broadcast and Multicast frames onto the wireless network.
C) The wired switch ports are set to Full Duplex and the controllers and APs are set to Auto
D) The WLAN frame types should not be mixed with S02.3 Ethernet.
E) Negotiate.
F) The wired network is using PoE over the data pairs of the Ethernet cables.
G) The WLAN is configured to use Spanning Tree Protocol (STP) in Fast Start mode.

3. You are deploying a WiNG 5 system and need to visualize Layer 1 activity only. Which of
the following tools would allow you to do this?

A) Protocol Analyzer
B) Predictive Site Survey tool
C) Manual Site Survey tool
D) WLAN Discovery tool
E) Spectrum Analyzer

4. You have configured Radio 2 (5 GHz) of an AP-650 to use 802.11n 20/40 MHz channels. Under the WLAN configuration settings you have selected WPA/WPA2-TKIP using a PSK. To test the connection you associate an 802.lln client laptop device but notice that the connection speed between the two 802.11n devices is limited to 54 Mbps. See Exhibit:
B.3.2.06 at the bottom. Which of the following is the most likely reason for this condition?

A) More wireless client devices are using 802.11a than are using 802.lln tipping the AP into legacy compatibility mode.
B) 802.11 Protection Mechanisms are in effect.
C) PSK is limited to 54 Mbps.
D) WPA/WPA2-TKIP encryption is limited to 54 Mbps.
E) Channels in the 5 GHz band are limited to 802.11a rates of 54 Mbps.

5. After setting up an outdoor WLAN in a tropical environment, the local administrator asks if weather effects were considered during the setup. Which of the following is true regarding the effect of bright sunlight and high temperatures on outdoor WLAN propagation?

A) Bright sunlight and high temperatures will have little or no effect.
B) The effect can be mitigated by placing the transmitter in a radome to protect it.
C) Bright sunlight and high temperatures will decrease the range.
D) Bright sunlight and high temperatures will introduce refraction causing the link not to work.
