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

質問 3：

質問 4：
You have just deployed a new Motorola RFS4000 / AP-650 WLAN and are preparing to test the results to make sure that its performance will match the customers expectations. Using a popular WLAN discovery application you sample the air interface in use by your WLAN. After locating the SSIDs assigned to the 2.4 GHz band, in the Discovery utility, you notice a similarity between the MAC addresses assigned to each SSID. Which of the following best explains this similarity?

A. Up to 16 sequential BSSIDs are available per radio.
B. Each ESSID has been automatically assigned to a different BSSID.
C. ESSIDs are assigned sequentially by the manufacturer.
D. BSSIDs are assigned to ESSIDs dynamically so they can change according to channel conditions.
E. Two ESSIDs have been assigned to the 2.4 GHz radio and two ESSIDs have been assigned to the 5 GHz radio.
正解：B

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

質問 6：
As part of the Acceptance Testing you will need to validate that the failover design of your RFS controllers is working. Your configuration is two RFS7000 controllers. To begin your test you first power-off your Primary RFS7000 controller and will now inspect the System Status LEDs on the RFS7000 controller that is configured as the backup system. If you system is configured and functioning correctly what is the expected current state of the System Status 2 LED? Please use the Status exhibit at the bottom.

A. Green Solid
B. Amber Blinking
C. Off
D. Alternating Green Blinking & Amber Blinking
E. Green Blinking
正解：B

質問 7：
You have been asked to cover a long narrow corridor and are determining the types of antennas to install. All of the following antennas are suitable for this location, EXCEPT:
A. Yagi
B. Wall mount Patch Antenna
C. Leaky Feeder
D. Omni Directional
正解：B

質問 8：
You have just conducted a throughput test using iPerf on a WLAN that shows a PHY signaling rate of 54 Mbps, however the average throughput rate shown in iPerf is only 23.5 Mbps. What is the most likely explanation for this condition?
A. This throughput speed is considered nominal.
B. This throughput rate could indicate a mismatch between Wi-Fi confidentiality algorithms.
C. This throughput rate indicates excessive out-of-band interference such as nearby cell phone towers.
D. This throughput rate indicates excessive user activity.
正解：A
