Which of the following describe the DHCP Discover message? 1. It uses FF:FF:FF:FF:FF:FF as a layer 2 broadcast. 2. It uses UDP as the Transport layer protocol. 3. It uses TCP as the Transport layer protocol. 4. It does not use a layer 2 destination address.

Answer: Option B

A client that sends out a DHCP Discover message in order to receive an IP address sends out a broadcast at both layer 2 and layer 3. The layer 2 broadcast is all Fs in hex, or FF:FF:FF:FF:FF:FF. The layer 3 broadcast is FF:FF:FF:FF:FF:FF, which means all networks and all hosts. DHCP is connectionless, which means it uses User Datagram Protocol (UDP) at the Transport layer, also called the Host-to-Host layer.
