Question

Which of the following wireless standards provides the STRONGEST encryption?

Options

AWPA2
BWPA
CWEP64
DWEP128

Explanation

WPA2 (Wi-Fi Protected Access 2) provides the strongest encryption among the listed options. It uses AES (Advanced Encryption Standard) with CCMP, which is considered highly secure. WPA (original) uses TKIP encryption, which is stronger than WEP but weaker than WPA2. WEP (Wired Equivalent Privacy) is the oldest and weakest standard - both WEP64 (40-bit key) and WEP128 (104-bit key) use the RC4 cipher with known vulnerabilities that allow the key to be cracked in minutes with readily available tools. WEP128 is stronger than WEP64 but both are considered broken and obsolete. WPA2 (and the newer WPA3) are the recommended standards for secure wireless networks.
