Which of the following describe the DHCP Discover message? It uses FF...
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 255.255.255.255, 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.

Which of the following describe the DHCP Discover message? It uses FF...
The correct answer is option 'B' - 1 and 2.
Explanation:
The DHCP (Dynamic Host Configuration Protocol) Discover message is the first step in the DHCP process. It is used by a client to discover available DHCP servers on the network and request an IP address lease. Let's go through each statement to understand why options 1 and 2 are correct.
1. It uses FF:FF:FF:FF:FF:FF as a layer 2 broadcast:
- This statement is correct. The DHCP Discover message is sent as a layer 2 broadcast, where the destination MAC address is set to FF:FF:FF:FF:FF:FF. This means that the message is sent to all devices on the local network segment.
2. It uses UDP as the Transport layer protocol:
- This statement is correct. The DHCP Discover message uses the UDP (User Datagram Protocol) as the transport layer protocol. UDP is a connectionless protocol that provides a simple way to send datagrams between devices. DHCP uses UDP port 67 for server-to-client communication and UDP port 68 for client-to-server communication.
3. It uses TCP as the Transport layer protocol:
- This statement is incorrect. DHCP does not use TCP (Transmission Control Protocol) as the transport layer protocol. TCP is a connection-oriented protocol that provides reliable and ordered delivery of data, which is not necessary for DHCP.
4. It does not use a layer 2 destination address:
- This statement is incorrect. The DHCP Discover message does use a layer 2 destination address, which is FF:FF:FF:FF:FF:FF. This address indicates a layer 2 broadcast, where the message is sent to all devices on the local network segment.
Therefore, the correct answer is option 'B' - 1 and 2, as both statements accurately describe the DHCP Discover message.
