Free CompTIA Network+ N10-008 Practice Question

Reducing the power level to limit the wireless signal range is the best approach for enhancing network security because it minimizes the chance of the signal being accessible from outside the intended coverage area, thus reducing the attack surface for potential intruders. Setting the power too high may extend the signal beyond the physical boundaries and could be exploited by attackers outside the premises. Disabling power altogether would result in no wireless network, which contradicts the purpose of having a Wireless Access Point.
