What feature allows or rejects client connections on a wireless network based on hardware addresses?

1. SSID broadcasting

2. MAC address filtering

3. WPA encryption

4. Channel selection

The correct answer is: MAC address filtering

The feature that allows or rejects client connections on a wireless network based on hardware addresses is MAC address filtering. This security measure uses the MAC (Media Access Control) addresses of devices as a form of identification on the network. When a device attempts to connect to the wireless network, the network checks its MAC address against a list of allowed addresses. If the MAC address is on the list, the device is permitted to connect; if not, it is denied access. This method is often used in conjunction with other security measures to enhance the overall protection of the wireless network. However, while MAC address filtering can provide an additional layer of security, it is not foolproof, as MAC addresses can be spoofed by malicious actors. In contrast, the other options represent different aspects of wireless networking. SSID broadcasting refers to the way the network name is transmitted to devices in range, while WPA encryption is a security protocol used to encrypt data over the network to protect it from eavesdropping. Channel selection involves choosing the frequency channel on which the wireless signal is transmitted, which can help avoid interference from other networks or devices. However, none of these features specifically focus on the identification of devices based on their hardware addresses, making MAC address filtering the appropriate answer
