Motorola Solutions Deploy WLAN Solutions - MSC-122 FREE EXAM DUMPS QUESTIONS & ANSWERS]

Question 1

You are installing an 802.11n wireless segment which is intended to support VoWLAN applications in the 5 GHz band. The network design document specifies that the signal strength supports at least MCS 4 and requires an SNR of 25 dB minimum. Using the chart shown in Exhibit B.3.2.09vl, and without taking into consideration additional requirements, what is the maximum noise floor that can be tolerated within these constraints?

A. 58 dB B. -83 dBm C. -108 dBm D. -58 dBm E. 25 dB

Question 2

During a recent throughput analysis test of your 802.11g network, you discovered that performance is poor in comparison to previous baselines. You discover that this is the result of 802.11b stations becoming associated with your access point. What option could you implement to eliminate 802.lib clients from attaching to your network?

A. Implement RTS/CTS at the access point B. Implement protection mechanisms C. Make 24 mbps a required data rate D. Change the channel used for the network

Question 4

As part of your Customer Acceptance Testing you would like to record the information from multiple RFS switches over a 24 hour period. Which of the following is the BEST way to accomplish this?

A. Enable SNMP reporting on each of the RFS switches and direct the reporting to your network SNMP logger. After your recording period gather the SNMP data file from the SNMP server B. Enable Syslog and record the 24 hours of data on the internal hard drive of each of the switches, after your recording period log in to each switch and gather the data files using ftp C. Enable Syslog on each of the RFS switches and direct the messages to an external Syslog server on your network PC D. The RFS switch automatically keeps 24 hours of system messages on the internal hard drive, this file can be accessed from the GUI at any time. After your recording period log into each switch and view the data files

Question 5

You have begun an upgrade to an existing Motorola WLAN that supports 802.11b/g clients only on channel 6. As a test, you have configured an independent AP7131 and set the 2.4 GHz radio to use channel 11- (eleven minus). While performing a throughput test from a laptop PC to the new AP650 you begin to receive complaints from the customer's users that their connection speeds have dropped significantly and in some cases they have even lost their connections completely. They have accused you and the new system of causing the service disruptions. Which of the following is MOST likely in this situation?

A. You have properly configured a non-overlapping channel. You are NOT responsible for the disruption. B. You have forgotten to disable Greenfield mode. You ARE responsible for the disruption. C. Since no WIPS is in use, there could be rogue devices nearby initiating a Denial of Service (DoS) attack against the Customers WLAN. You are NOT responsible for the disruption. D. You have configured Channel Bonding in 2.4 GHz. You ARE responsible for the disruption. E. You have physically placed the new AP too close to the existing APs. You ARE responsible for the disruption. F. You have properly installed compatibility options on the 802.11n AP. You are NOT responsible for the disruption.

Question 6

After the initial deployment of a customer's WLAN you attempt to verify that test AP Radios 1 and 2 are operational. You have assigned Radio 1 (2.4 GHz) to use the SSID "WLAN1" and Radio 2 (5 GHz) to use the SSID "WLAN2". You perform a simple site survey using LANPlanner. LANPlanner plots the signal strength footprint of WLAN1 with no problem but WLAN2 does not show up in the LANPlanner heat map display. Based on the Wireless Configuration screen shown in Exhibit B.3.2.02 at the bottom, what are the most likely causes of this condition (select TWO)?

A. The Answer Broadcast Probes feature has been disabled B. The SSID has been assigned to the wrong VLAN C. The "default" QoS policy is in use. D. The Broadcast SSID feature has been disabled. E. The current configuration has not been pushed to the AP. F. The Allow RADIUS Override feature has been disabled.

Question 7

After implementing a WLAN you determine that the results are not what were anticipated. You observe with a protocol analyzer that certain stations are changing their modulation type and coding sequence. Why would a client device change its modulation type and coding sequence in a production environment?

A. To change its channel B. To change its data transfer speed C. To decrypt a data packet D. To change its power usage

Question 8

After the site survey and installation are complete, you perform a spot check to ensure performance compliance with the site survey. Which of the following should NOT be verified in this spot check?

A. Is the actual coverage as expected? B. Is roaming operating as predicted? C. Is the data properly secured? D. Is throughput what was expected?

Question 10

After deploying a new 802.11n WLAN you use a popular WLAN Discovery tool to analyze the channel settings being used in the vicinity. Using the information shown in the image below, which of the following statements is CORRECT concerning the use of channels in this area?

A. MAC address nex-G:6c:32:a2 is using an 802.11b-only reserved channel. B. SSID WLAN1a is using 36 MHz channels C. MAC address KENDIN:cf:ca:7d is using a channel which is illegal in ETSI nations. D. SSID Zinc is using 20/40 MHz channels 149 and 153
