Refer to the exhibit. Based on the debug ip dhcp server packet output, which statement is true?
- The client accepts the offer from the DHCP server for the 10.1.10.21 IP address.
- The client sends a DHCPREQUEST that contains IP address 10.1.10.21 to the DHCP server.
- The client sends a DHCPDISCOVER that contains IP address 10.1.10.21 to the DHCP server.
- The client sends the BOOTREPLY broadcast message to inquire for a new IP address.
Explanation: The provided output demonstrates the standard four-way DHCPv4 handshake, often called the "DORA" process (Discover, Offer, Request, Acknowledgment). After the server sends a DHCPOFFER to provide the client with the IP address 10.1.10.21, the server receives a DHCPREQUEST from that same client.
In the DHCP operational model, the DHCPREQUEST message is specifically used by a client to choose or accept the specific IP address and configuration parameters that were provisionally assigned in the server's offer. While the request is being broadcast to inform all potential servers of its choice, it serves as the formal acceptance of the 10.1.10.21 offer. Following this acceptance, the server finalizes the binding by sending a DHCPACK.
