Question

A technician has noticed that a client has an unsecured wireless network. Which of the following is the BEST security encryption type to protect the wireless network from intrusion?

Options

AWEP2
BWEP
CWPA2
DWPS

Explanation

WPA2 (Wi-Fi Protected Access 2) is the strongest encryption option listed, using AES (Advanced Encryption Standard) with CCMP, which provides robust, modern security for wireless networks. WEP (Wired Equivalent Privacy) is severely outdated and can be cracked in minutes using widely available tools - it should never be used. WEP2 is not a recognized, standardized wireless security protocol and does not exist as a real security option. WPS (Wi-Fi Protected Setup) is a convenience feature for easy device pairing, not an encryption protocol, and it has well-documented vulnerabilities (WPS PIN brute-force attacks). Therefore, WPA2 is the best available choice among the options provided.
