In terms of DHCP messages, what causes a DHCP server to respond with a DHCPNACK message and what happens when a DHCP client receives such DHCP message? (Choose two)
the client will send a DHCPDECLINE message to the server and restart the configuration process by going into the Requesting state.
the client restarts the configuration process by going into the Requesting state.
the client will send a DHCPDISCOVER message
the server is unable to satisfy a DHCPDISCOVER message
the server is unable to satisfy a DHCPREQUEST message
There are four basic steps in DHCP client IP address requests from the server. A DHCP client sends a DHCPDISCOVER broadcast message to locate a Cisco IOS DHCP server. Then, a DHCP server will offer configuration parameters to the client in a DHCPOFFER unicast. The client then will return a request for the offered IP address to the DHCP server in a DHCPREQUEST broadcast message. After which the DHCP server confirms with a DHCPACK unicast message to the client. However, there would be a situation when a DHCP server is unable to satisfy a DHCPREQUEST message, thus, responds with a DHCPNACK message. After receiving such message, the client restarts the configuration process by going into the Requesting state.
