What sequence of actions does a DHCP client take when re-accessing a network?

When a DHCP client re-accesses a network, it typically goes through a process that begins with sending out a DHCP Discover packet. This packet is a broadcast message that informs any available DHCP servers on the network that the client is seeking an IP address and additional network configuration.

Upon receiving the DHCP Discover packet, one or more DHCP servers respond with a DHCP Offer packet. This packet includes an available IP address, subnet mask, lease duration, and possibly other configuration parameters. The client then has the ability to select one of the offers it received, which it does by sending a DHCP Request packet back to the server, indicating its choice of the offered IP address.

This initial stage of sending the Discover and receiving the Offer ensures that the client can confirm its network connection and obtain an appropriate IP address for effective communication on the network. Thus, this process is essential, and the correct answer reflects the standard operation of the DHCP protocol when a client re-initiates its connection to a network.
