"Client Addressing Information in DHCP Server Response"

A client requests a new dynamic address and receives a response from two DHCP servers.

Which of the following addressing information would the client use?

A.

The IP addressing information received last

B.

The IP addressing information from the highest server MAC address

C.

The IP addressing information from the highest server IP address

D.

The IP addressing information received first.

D.

When a client requests a new dynamic address, it sends a DHCPDISCOVER message to the network. DHCP servers on the network reply to the client with a DHCPOFFER message, which includes IP addressing information that the client can use.

In this scenario, the client has received a response from two DHCP servers. The client can use the IP addressing information received first, which is option D. This is because the client will typically accept the first DHCPOFFER message it receives and send a DHCPREQUEST message to the server that made the offer. The client will then receive a DHCPACK message from the selected server, confirming the IP addressing information that has been assigned.

Options B and C suggest that the client should choose the IP addressing information based on the MAC or IP address of the DHCP server. However, DHCP clients do not use these criteria to select an IP address. Instead, they typically accept the first offer they receive.

Option A suggests that the client should use the IP addressing information received last, but this is not a typical behavior of DHCP clients.

Therefore, the correct answer is D: the client should use the IP addressing information received first.
