Which DHCPv4 message will a client send to accept an IPv4 address offered by a DHCP server?

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

Answer: (C)

When a client is assigned an IPv4 address by a DHCP server, it will send a DHCPREQUEST message to indicate acceptance of the offered address. This procedure is part of the DHCP lease process. After the client receives a DHCPOFFER from the DHCP server, which contains the proposed IP address and configuration parameters, it must specify which offer it is accepting if there are multiple offers. By sending the DHCPREQUEST, the client not only informs the server to confirm the selected address but also implicitly declines any other offers it might have received. This process is crucial for ensuring that the client successfully establishes a lease for the assigned IP address. The DHCPACK message that follows is sent by the DHCP server to confirm that the lease has been granted. Given this flow, the DHCPREQUEST message is pivotal in the communication between the client and the server, making it the correct choice.
