What action does a DHCPv4 client take if it receives more than one DHCPOFFER from multiple DHCP servers?

• A. It sends a DHCPDISCOVER to all servers
• B. It accepts the first DHCPOFFER it receives
• C. It sends a DHCPREQUEST that identifies which lease offer the client is accepting
• D. It ignores all DHCPOFFER messages

Answer: (C)

When a DHCPv4 client receives multiple DHCPOFFER messages from different DHCP servers, the client follows a specific process to choose one of those offers. The correct response is for the client to send a DHCPREQUEST message. This message is used to inform the selected server which lease offer the client has accepted. By sending the DHCPREQUEST, the client is also indirectly informing the other DHCP servers that their offers have been declined, as only one offer can be accepted at a time. This action ensures that the selected server can finalize the lease of the IP address for the client. The DHCPREQUEST effectively formalizes the acceptance of the offer and allows for proper communication for lease management. This systematic approach is essential for maintaining orderly IP address allocation and avoids potential conflicts that could arise from a client trying to use multiple addresses at the same time. Through this process, the DHCP client ensures that it operates efficiently within the network, utilizing a structured and standardized method for obtaining IP configuration.
