In a DHCP interaction, what does DORA stand for?

Correct answer: Discover, Offer, Request, Acknowledge

Option B is correct because DORA is the acronym for the four-step DHCP IP address assignment process: Discover (client broadcasts to find DHCP servers), Offer (server responds with an available IP), Request (client formally requests the offered IP), and Acknowledge (server confirms the lease). Option A is wrong because Destination, Origin, Route, Address is not a real networking acronym and does not describe any DHCP or networking process. Option C is wrong because Download, Obtain, Request, Assign does not correspond to any phase of the DHCP process; these terms have no defined meaning in the DHCP specification. Option D is wrong because Domain, Obtain, Register, Assign conflates DNS and DHCP concepts and does not reflect the actual DHCP exchange sequence defined in RFC 2131.
