Which option shows the correct sequence of the DHCP packets that are involved in IP address assignment between the DHCP client and the server?
Click on the arrows to vote for the correct answer
A. B. C. D. E.B.
The correct sequence of DHCP packets that are involved in IP address assignment between the DHCP client and server is:
B. DISCOVER, OFFER, REQUEST, ACK
Here is a detailed explanation of each step in the sequence:
DISCOVER: The DHCP client broadcasts a DHCPDISCOVER message on the network to discover available DHCP servers. This message contains information about the client, such as its MAC address and the network it is connected to.
OFFER: DHCP servers on the network receive the DHCPDISCOVER message and respond with a DHCPOFFER message, which contains an available IP address for the client to use. This message also includes other information, such as the subnet mask and the IP address of the DHCP server.
REQUEST: The DHCP client selects one of the IP addresses offered by the DHCP servers and sends a DHCPREQUEST message requesting the use of that IP address. This message also confirms the other configuration parameters that were offered in the DHCPOFFER message.
ACK: The DHCP server receives the DHCPREQUEST message and sends a DHCPACK message to the client, confirming the IP address lease and other configuration parameters. The DHCPACK message also includes the lease time for the IP address, which specifies how long the client can use the IP address before it must be renewed.
Note that options A, C, and D are incorrect because they contain incorrect or incomplete sequences of DHCP packets. Option E is incorrect because it includes the DISCOVER message after the REQUEST message, which is not a valid sequence.
