What is one advantage of using WPA over WEP?

1. WPA requires less processing power

2. WPA is more easily configurable

3. WPA provides stronger encryption

4. WPA does not require a password

The correct answer is: WPA provides stronger encryption

WPA provides stronger encryption compared to WEP due to the use of more advanced security protocols. WEP relies on a static encryption key and uses RC4 stream cipher encryption, which has been found to be vulnerable to several types of attacks. In contrast, WPA uses TKIP (Temporal Key Integrity Protocol) and later WPA2 incorporates AES (Advanced Encryption Standard), which are designed to address the weaknesses of WEP and offer dynamic encryption keys that change periodically. This makes it significantly more difficult for attackers to decrypt the traffic over a WPA-protected network, providing a higher level of data protection and integrity. The other options do not capture the main advancements that WPA brings in terms of security. While WPA may be easier to configure than WEP in some contexts or require more processing power than WEP, these factors are secondary to its primary benefit of stronger encryption. Furthermore, WPA does require a password for network access, which is not a feature of its advantages.
