You Are Designing a Wireless LAN with the Following Components

question 280

Multiple Choice

You are designing a wireless LAN with the following components: 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:

Selection Bias

A problem in experimental design stemming from the experimental groups not being comparable.

Spurious Relationships

A connection between two variables that appears causal but is actually caused by a third variable.

Experimental Situation

The setting experimental subjects are placed in. This setting may be a threat to external validity if it does not reflect external reality.

External Validity

Relates to whether an experiment has in fact captured the external world that the researcher is investigating.
