Motorola Solutions Deploy WLAN Solutions 認定 MSC-122 試験問題:

1. You are performing a physical site survey of a new WiNG 5 WLAN deployment. Which of the following is CORRECT?

A) Using default settings of a site survey application will provide an adequate site survey result.
B) It is acceptable that you use any RF infrastructure device (Access Point) to perform the site survey test.
C) The Signal to Noise Ratio (SNR) is a critical measurement that needs to be addressed.
D) Customer throughput requirements are the only criteria for which need to be surveyed.

2. A new WLAN customer is trying to implement a secure 802.11n wireless LAN. As part of the testing, 802.11n data rates cannot be achieved. Which of the following encryption standards support 802.11n data rates?

A) 802.11i (AES)
B) Keyguard
C) WEP
D) TKIP

3. When the original site survey was performed using predictive software, the primary concern was data rate. You are onsite performing the installation, the network administrator informs you there was a miscommunication, and the primary concern is signal strength, not data rate. When you perform the survey again with predictive software how should it be carried out?

A) Perform a separate prediction for 802.11b and 802.llg.
B) Perform a combined prediction for 802.11b and 802.11g.
C) Perform neither separate nor combined predictions; predictive software is ineffective in this case.
D) Perform both separate and combined predictions to see the effects of their interaction.

4. You are in the process of mounting access point antennas for a new system. Which of the
following is CORRECT?

A) The antenna polarization plays an important role in proper RF signal propagation
B) They can be oriented in any manner
C) Patch antennas must be used in outdoor applications
D) You should use the same antennas for all access points

5. Your customer has requested that during the upcoming 802.llg to 802.11n upgrade deployment you enable 40 MHz channels on 1, 6, and 11 of the 2.4 GHz ISM band. You respond by saying that there is not enough spectrum to allow 40 MHz channels centered on 1, 6, and 11. How wide are standard 802.11g (OFDM) channels?

A) 20 MHz
B) 22 MHz
C) 11 MHz
D) 5 MHz
E) 83.5 MHz
