Which of the following describe the DHCP Discover message?<br>1. It uses <code class="args"><em>FF:FF:FF:FF:FF:FF</em></code> as a layer 2 broadcast.<br>2. It uses UDP as the Transport layer protocol.<br>3. It uses TCP as the Transport layer protocol.<br>4. It does not use a layer 2 destination address.

Correct Answer: 1 and 2
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.
