Question

A network technician is setting up a secure WAP for a small office. The owner insists on using the best security available. Which of the following techniques would BEST protect this WiFi setup?

Options

AWPA2 TKIP
BWEP
CWPA2 AES
DWPS

Explanation

WPA2 with AES provides the strongest WiFi security among the listed options. WPA2 superseded both WPA and WEP, and AES (Advanced Encryption Standard) is a significantly stronger cipher than TKIP (Temporal Key Integrity Protocol), which has known cryptographic weaknesses and is deprecated. WEP (Wired Equivalent Privacy) is obsolete and can be cracked in minutes with readily available tools. WPS (Wi-Fi Protected Setup) has a well-documented PIN brute-force vulnerability and should be disabled, not relied upon as a security mechanism. For best protection, WPA2-AES (or WPA3 if available) is always preferred.
