In DHCP, which sequence represents the correct order of messages from discovery to acknowledgement?

• A. DHCP Discover → DHCP Offer → DHCP Request → DHCP Acknowledge
• B. DHCP Offer → DHCP Discover → DHCP Request → DHCP Acknowledge
• C. DHCP Discover → DHCP Request → DHCP Offer → DHCP Acknowledge
• D. DHCP Acknowledge → DHCP Discover → DHCP Offer → DHCP Request

Answer: (A)

DHCP assigns an IP address through a four-step message sequence: the client first broadcasts a Discover to locate any DHCP server on the network. The server responds with an Offer that includes a proposed IP address and other network parameters. The client then sends a Request to accept a specific offered address and parameters. Finally, the server sends an Acknowledge to confirm the lease and finalize the configuration. This order is essential because the client must see an offer before committing to a particular address, and the server must acknowledge the lease to complete the setup.
