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.
Answers Explanation & Hints:
When a DHCPv4 client receives more than one DHCPOFFER message from multiple DHCP servers, it will select one of the offers and send a DHCPREQUEST message to the selected DHCP server to request the lease offer. The DHCPREQUEST message identifies the lease offer the client is accepting and declines the other offers. The selected DHCP server responds with a DHCPACK message to confirm the lease. This process is called DHCPv4 offer selection, and it helps the client to choose the most appropriate DHCP server and avoid IP address conflicts that might occur if it accepts multiple offers. Therefore, the correct option is: It sends a DHCPREQUEST that identifies which lease offer the client is accepting.
