What is the DHCP DORA process, and what happens if a DHCP client sends a DHCP Request after receiving Offers from multiple servers?

• A.DORA stands for: Discover, Obtain, Renew, Acknowledge; the Request step is only used during lease renewal
• B.If multiple servers respond, the client uses the last received Offer; the DHCP Request goes only to that server as unicast
• C.DORA: Discover (broadcast from client), Offer (unicast or broadcast from each DHCP server with a proposed IP), Request (broadcast from client - specifying which server's offer it accepts, by Server Identifier option), Acknowledge (from the chosen server, confirming the IP lease). The broadcast Request is important: other DHCP servers see it, realize their offer was declined, and release the tentatively reserved address back to their pool
• D.If multiple DHCP servers respond, the client must contact each server and decline all but one; there is no broadcast mechanism
