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

1. On a new WiNG 5 RFS controller, you have configured six VLANs and assigned them to WLANs. The WLANs have been assigned to radios and security settings have been enabled. You have committed the changes and saved the Running Configuration settings to the Startup Configuration file. After moving the RFS controller from the staging area into the production area, you notice that newly adopted APs do not have the correct settings. Which of the following is the MOST likely reason for this condition?

A) Configuration changes were made at the device level.
B) Configuration changes must be committed individually after each AP is adopted.
C) Wi-NG 5.x RFS controllers cannot be relocated after the configuration changes have been committed.
D) A security policy has overwritten the device settings.
E) The master AP that stores the configuration changes is on a separate VLAN.

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

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

4. Which of the following statements is NOT considered to be a best practice with respect to the wired backbone serving the WLAN?

A) When creating a link between Gigabit Ethernet fiber ports, disable auto-negotiation on both ports.
B) When creating a link between Gigabit Ethernet fiber ports, enable (or accept the default of) auto-negotiation.
C) When creating a link between Ethernet 10/100BASE-T or 10/100/1000BASE-T ports, enable (or accept the default of) auto-negotiation on both ports.
D) When performing manual configuration of a point-to-point Ethernet link, ensure that both the speed and the duplex mode settings on the two ports match.

5. Configuring the down tilt of an antenna is important for certain applications and antenna types. For which antenna type is down tilt most important?

A) Grid
B) Dipole
C) Parabolic dish
D) Panel
