DHCP Request is ...?

• A. Client accepting the offer.
• B. Server offering an IP address.
• C. A client requesting an IP address.
• D. Server confirming assignment.

Answer: (A)

In DHCP, the client goes through Discover → Offer → Request → Acknowledge. The DHCPREQUEST is sent by the client after it has received one or more offers and has chosen to use a particular IP address. This message conveys the client’s acceptance of the selected offered IP and requests the server to lease that address to the client. The server that sent the chosen offer will respond with DHCPACK to finalize the assignment.

So the action described by the DHCPREQUEST is the client accepting the offer. The other ideas map to different parts of the flow: the server offering an IP is the Offer, the client simply requesting an IP in general is covered by the initial Discover/Request sequence, and the server confirming the assignment is the DHCPACK.
