Which of the following is an advantage of using WPA2 instead of WPA3?
Correct Answer:
C
Device compatibility is an advantage of using WPA2 instead of WPA3. WPA2 is the previous version of the Wi-Fi Protected Access protocol, which provides security and encryption for wireless networks. WPA3 is the latest version, which offers improved security features, such as stronger encryption, enhanced protection against brute-force attacks, and easier configuration. However, WPA3 is not backward compatible with older devices that only support WPA2 or earlier protocols. Therefore, using WPA3 may limit the range of devices that can connect to the wireless network. Connection security, encryption key length, and offline decryption resistance are advantages of using WPA3 instead of WPA2. References:
