Which feature is provided by WPA2 on a wireless network?

1. Firewall protection

2. Encryption

3. MAC address filtering

4. Bandwidth management

The correct answer is: Encryption

WPA2, or Wi-Fi Protected Access II, is a security protocol widely used to secure wireless networks, and its core feature is encryption. It uses the Advanced Encryption Standard (AES) to encrypt data transmitted over the wireless network, ensuring that any data sent between the wireless device and the access point is protected from unauthorized access. By encrypting the data, WPA2 helps to safeguard sensitive information and protects users against eavesdropping and other forms of cyber threats. While other features like firewall protection, MAC address filtering, and bandwidth management are important aspects of network security and performance, they are not functions provided by WPA2 itself. Firewalls control incoming and outgoing network traffic, MAC address filtering restricts network access based on hardware addresses, and bandwidth management prioritizes traffic based on set rules. These features may complement WPA2 in enhancing overall network security and efficiency but are not intrinsic to the WPA2 protocol.
