SY0-301 · Question #317
A perimeter survey finds that the wireless network within a facility is easily reachable outside of the physical perimeter. Which of the following should be adjusted to mitigate this risk?
The correct answer is D. Power level controls. Wireless access points allow administrators to adjust transmit power. Reducing the power level shrinks the radio frequency (RF) coverage area so the signal does not propagate beyond the physical building, preventing outsiders from reaching the network. CCMP is the encryption prot

Explanation
Wireless access points allow administrators to adjust transmit power. Reducing the power level shrinks the radio frequency (RF) coverage area so the signal does not propagate beyond the physical building, preventing outsiders from reaching the network. CCMP is the encryption protocol used by WPA2 - it secures data but does not change signal reach. MAC filtering restricts which devices can associate but does not stop the signal from being received and probed. Disabling SSID broadcast hides the network name but the signal is still detectable. Only power level controls directly limit the physical coverage area.
