process?

A.
Discover, offer, request, acknowledge.

B.
Request, discover, offer, acknowledge.

C.
Offer, acknowledge, request, discover.

D.
Discover, request, offer, acknowledge.

Explanation:
Think DORA. The first packet that goes out is a discovery packet which has the responsibility to
seeking out and discovering a DHCP server. It is the request saying that: “hey – I need an IP
address”. The DHCP server, or servers if there are more than one, may offer an IP address to the
client. The client, will receive the offer, and if there are more than one DHCP server, the client will
receive multiple offers. The client must now choose from the available offers (usually takes the first
offer to make it simple) and now makes the formal request, saying: “May I have this IP address”.
Finally, the DHCP server should acknowledge and say: ‘Yes”. Note that it is possible that the

DHCP server timed out and gave the address away to someone else, so the acknowledgement is
important.
