1 only
1 and 2
3 and 4
4 only
Answer: Option
Explanation:
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.

Layer 2 broadcast layer is for mac address configuration.

Layer 3 in router is for configuring the routing table. DHCP is for the total message.
