question 282

Multiple Choice

You are designing a wireless LAN with the following components: - High-density indoor access point deployment - 2.4-GHz and 5-GHz radios - 802.11a, 802.11g, and 802.11n mode wireless LAN clients Site survey results show negligible foreign WiFi and non-WiFi interference. What is the best method to decrease duty cycle (radio frequency utilization) and increase overall wireless LAN client performance for this design?

• A) Disable all data rates below 12 Mb/s on all access points.
• B) Decrease radio transmit power on all access points that report a high duty cycle.
• C) Increase radio transmit power on all access points that report a high duty cycle.
• D) Disable all data rates above 12 Mb/s on all access points.
• E) Increase radio transmit power on all access points.

Definitions:

P-value

A measure in statistics that helps determine the significance of results, indicating the probability of observing the given result by chance if the null hypothesis is true.

F-to-enter

A criterion used in multiple regression analysis to decide at which level a new variable should be included in the model.

Residuals Plots

Graphs used to visualize the residuals of a data set against predicted values, helping to assess the fit of a model.

Analysis of Variance

A statistical method used to test differences between two or more means.
