You are reporting on the RF environment in you facility. The manager asks you do describe the noise floor noted in the report. Which of the following is the best explanation?

A.

The energy radiated by flooring materials that causes interference in the 2.4 GHz and 5 GHz bands.

B.

The noise caused by elevators, microwave ovens, and video transmitters.

C.

The RF energy that exists in the environment from intentional and unintentional RF radiators that forms the baseline above which the Intentional signal of your WLAN must exist.

D.

The extra energy radiated by access points and client devices beyond that intended for the signal.

You are troubleshooting a client issue on a Windows laptop. The laptop can see and connect to 2.4 GHz APs, but is does not even see 5 GHz APs. While evaluating the issue, you determine that this problem is happening for all of the laptops of this model in the organization. Several other tablets connect on channel 48 and channel 52 in the same work areas. What is the likely problem?

A.

The clients are configured to use WPA and 5 GHz channels only support WPA2.

B.

The antennas in the laptop have insufficient gain to detect the 5 GHz signals.

C.

The access points are configured to disallow 5 GHz.

D.

The client drivers are faulty and should be upgraded.

A string of characters and digits is entered into an AP a client STA for WPA2 security. The string is 8 characters long. What is this string called?

What statement about the beamwidth of an RF antenna is true?

A.

Horizontal and vertical beamwidth are calculated at the point where the main lobe decreases power by 3 dB.

B.

Vertical beamwidth is displayed (in degrees) on the antenna’s Azimuth chart.

C.

When antenna gain is lower, the beamwidth is also lower in both the horizontal and vertical dimensions.

D.

The beamwidth patterns on an antenna polar chart indicate the point at which the RF signal stops propagating.

Your manager asked you to locate a solution that allows for centralized monitoring of WLAN performance over time. He wants a single pane of glass for administration and monitoring of the solution. What do you recommend?
