Which statements about DHCP are true? (Choose three.)

• DHCP messages use UDP as a transport protocol.
• The DHCPOFFER message is sent by the DHCP server after receiving a DHCPDISCOVER message from a client.
• DHCP uses ports 67 and 68.
• The DHCPREQUEST message is sent by a DHCP client to locate a DHCP server.
• The DHCPACK message is sent by the DHCP server to provide the DHCP client with the DHCP server MAC address for further communications.
• All DHCP communications are broadcast.

Explanation: DHCP uses User Datagram Protocol (UDP) as its transport protocol. The client sends messages to the server on port 67. The server sends messages to the client on port 68. When the DHCP server receives a DHCPDISCOVER message, it finds an available IP address to lease, creates an ARP entry consisting of the MAC address of the requesting host and the leased IP address, and transmits a binding offer with a DHCPOFFER message. The DHCPOFFER message is sent as a unicast, using the server’s Layer 2 MAC address as the source address and the client’s Layer 2 address as the destination.
