What is the correct sequence of steps followed by a DHCP client to obtain an IP address?

• A. DHCPDiscover, DHCPRequest, DHCPOffer, DHCPAck
• B. DHCPOffer, DHCPRequest, DHCPAck, DHCPDiscover
• C. DHCPOffer, DHCPDiscover, DHCPRequest, DHCPAck
• D. DHCPRequest, DHCPAck, DHCPDiscover, DHCPOffer

Answer: (A)

The sequence of steps followed by a DHCP client to obtain an IP address begins with the DHCPDiscover message, which is sent by the client to locate available DHCP servers on the network. This is crucial because the client needs to find out which DHCP servers are available to provide an IP address. Next, upon receiving the DHCPDiscover message, a DHCP server responds with a DHCPOffer message. This message includes an available IP address along with other configuration parameters that the server is offering to the client. This offer indicates the server's willingness to lease the offered IP address to the client. The client then sends a DHCPRequest message back to the server, indicating that it has accepted the offer and is requesting the specific IP address that has been offered. This step is essential because multiple DHCP servers may have responded to the initial discover message; therefore, the request specifically acknowledges the preferred server's offer. Finally, the server responds with a DHCPAck message, confirming that the IP address has been allocated to the client for its use. This acknowledgment completes the process, and at this point, the client can proceed to use the assigned IP address for communication on the network. This sequence reflects the correct and standard interaction between a DHCP client and server, ensuring that the client properly
