Answer:

both MAC and IPv4 addresses of the DHCP server

FF-FF-FF-FF-FF-FF and IPv4 address of the DHCP server

FF-FF-FF-FF-FF-FF and 255.255.255.255

MAC address of the DHCP server and 255.255.255.255

Explanation:

When the lease of a dynamically assigned IPv4 address has expired, a workstation will send a DHCPDISCOVER message to start the process of obtaining a valid IP address. Because the workstation does not know the addresses of DHCP servers, it sends the message via broadcast, with destination addresses of FF-FF-FF-FF-FF-FF and 255.255.255.255.

Answer:

FF-FF-FF-FF-FF-FF and 255.255.255.255

Explanation:

At the expiration of the assigned IPV4 address, the work station will send a DHCPDISCOVER message so as to initiate the process of getting an authentic IP address. This is because the workstation cannot identify the DHCP serves address.

The second layer address broadcast FF-FF-FF-FF-FF-FF is adopted on the ethernet frame and is assumed to be broadcasted on all equipment.

255.255.255.255 is the 3rd layer address used to label the exact same host.
