DHCPACK: what does it indicate?

• A. The DHCP server confirming that the address lease has been accepted
• B. The client requesting to renew an address
• C. A client initiating a message to find a DHCP server
• D. The server offering an IP address

Answer: (A)

DHCPACK is the server’s confirmation that the client’s requested IP configuration has been accepted and is being applied. After the client discovers a server and the server offers an IP lease, the client requests to use that configuration. The server replies with DHCPACK to finalize the lease and provide the exact network parameters (IP address, subnet mask, default gateway, DNS servers, lease duration). Receiving the ACK means the client can configure its network interface with these values and start using the address. If the client is renewing a lease, it would send a renewal request, and the server would respond with DHCPACK or DHCPNAK accordingly. The other messages in the sequence—discovery and offer—are about finding a server and proposing a lease, not about final acceptance.
