220-802 Question #696: Real Exam Question with Answer & Explanation

The correct answer is C: Radio power adjustment. Reducing the radio transmit power (radio power adjustment) limits how far the wireless signal propagates, keeping it within the intended area and reducing bleed into adjacent offices. This directly shrinks the attack surface available to third parties. Switching between 802.11b,

Question

A technician is having issues with a corporate wireless signal bleeding into nearby offices. Which of the following techniques could be used to mitigate the risk of wireless attacks by third parties in the nearby offices?

Options

ASwitch from 802.11b to 802.11g spectrums
BDisable WEP-128 security
CRadio power adjustment
DSwitch from 802.11g to 802.11n spectrums

Explanation

Reducing the radio transmit power (radio power adjustment) limits how far the wireless signal propagates, keeping it within the intended area and reducing bleed into adjacent offices. This directly shrinks the attack surface available to third parties. Switching between 802.11b, g, or n changes throughput and frequency band but does not significantly reduce signal range. Disabling WEP-128 would actually remove encryption, making the network less secure, not more.
