Question

You may have noticed that the DHCP request that Phil-F¢s iMac sends is a broadcast packet, sent to Ethernet address: ff:ff:ff:ff:ff:ff, and IP address: 255.255.255.255. But when his iMac sends the DHCP request it has already selected an IP address and it knows which server the selected offer came from.Why does it send the request as a broadcast packet?A. This way all DHCP servers on the network will get a copy of it, so they can withdraw other offers that were not selected.B. All DHCP servers must get a copy of the request so they can update their mappingsC. DHCP is a distributed protocol and the broadcast packets ensures that servers are synchronizedD. There is a mistake in the implementation; the DHCP request should be a unicast packet.

Answer 1

Answer:

C. DHCP is a distributed protocol and the broadcast packets ensure that servers are synchronized.

Explanation:

DHCP (dynamic host configuration protocol) is a server based protocol that provides clients or nodes in a network with dynamically configured services such as assigning ip addresses, DNS, default gateway etc.

It is a broadcast protocol, given that for a client to seek services from a server, it sends a broadcast traffic to the server or servers in the network. The dhcp protocol forwards this message to all the servers to synchronize them, so only one server responses to the request and the servers updated.
