Final answer:
WPA2 on a wireless network supplies encryption and DHCP; however, encryption is the security-related feature, while DHCP is a network management feature.
Step-by-step explanation:
The features supplied by WPA2 on a wireless network include B) Encryption and D) DHCP. WPA2 stands for Wi-Fi Protected Access 2 and is a security protocol designed to provide a secure wireless connection. It secures the network by encrypting data transmitted over the airwaves, thus preventing unauthorized access and ensuring that the data cannot be intercepted and read by others. Unlike MAC filtering, which can be bypassed and does not encrypt data, and port forwarding, which is related to directing traffic to specific devices on a network, encryption is a core feature of WPA2. DHCP, or Dynamic Host Configuration Protocol, while often used in conjunction with wireless networks to dynamically assign IP addresses, is not a security feature and is not specific to WPA2.
