What action does a DHCPv4 client take if it receives more than one DHCPOFFER from multiple DHCP servers?
- It sends a DHCPREQUEST that identifies which lease offer the client is accepting.
- It sends a DHCPNAK and begins the DHCP process over again.
- It accepts both DHCPOFFER messages and sends a DHCPACK.
- It discards both offers and sends a new DHCPDISCOVER.
| Explanation & Hint:
When a DHCPv4 client receives more than one DHCPOFFER from multiple DHCP servers, it will choose one offer based on its own selection criteria (which could be the first offer received or the best offer based on certain metrics such as lease time or server preference). The client then sends a DHCPREQUEST message back to the network to identify which lease offer it is accepting. This request is broadcast to all DHCP servers to let any other servers that might have made offers know that their offer is not being accepted. The server whose offer was accepted will respond with a DHCPACK, completing the process. |
