Which DHCP message type confirms that the address lease has been accepted?

• A. DHCPOFFER
• B. DHCPACK
• C. DHCPREQUEST
• D. DHCPDISCOVER

Answer: (B)

The DHCPACK message type is used to confirm that the address lease has been accepted. When a client sends a DHCPREQUEST message, it is essentially requesting an IP address that it has previously received in the DHCPOFFER from a DHCP server. After this request, the DHCP server responds with a DHCPACK, indicating that the lease is granted and the client can use the assigned IP address for the designated duration. This process ensures that both the client and server are in agreement about the lease of the IP address. The DHCPACK is key to establishing a relationship between the client and the server with respect to the IP address assigned, as it signifies the successful completion of the DHCP lease process. In contrast, the DHCPOFFER is the initial message sent by the DHCP server to inform clients of available IP addresses, while the DHCPREQUEST is sent by the client to request an IP address formally. DHCPDISCOVER is the initial broadcast message that clients use to locate DHCP servers on the network. This distinction is crucial as it illustrates the sequential flow of the DHCP process, culminating in the DHCPACK that solidifies the lease agreement.
