An engineer is deploying outdoor Cisco Aironet 1500 Series Access Points and wants to protect the network from overvoltage transients. Which two protection methods must be used? (Choose two)
The correct answer is A. lightning arrestor B. grounding lug. Outdoor APs are exposed to environmental hazards including lightning strikes, which can cause damaging overvoltage transients on antenna cables and cabling infrastructure. A lightning arrestor (A) is installed on the RF/coax cable between the antenna and AP to divert surge…

Explanation
Outdoor APs are exposed to environmental hazards including lightning strikes, which can cause damaging overvoltage transients on antenna cables and cabling infrastructure. A lightning arrestor (A) is installed on the RF/coax cable between the antenna and AP to divert surge energy safely to ground, protecting sensitive electronics. A grounding lug (B) provides a low-impedance path to earth ground, ensuring that any induced electrical charge is safely dissipated rather than damaging the AP or connected equipment. Together, these are the standard and required methods for overvoltage protection on outdoor wireless deployments. Antenna diversity improves signal reliability, temperature control protects against heat, and PoE output is a power delivery mechanism-none of these protect against overvoltage transients.
