A.R1 will forward the packet out all interfaces.
B.R1 will drop this packet because this it is not a valid IP address.
C.As R1 forwards the frame containing this packet, Sw-A will add 192.168.1.255 to its MAC table.
D.R1 will encapsulate the packet in a frame with a destination MAC address of FF-FF-FF-FF-FF-FF
E.As R1 forwards the frame containing this packet, Sw-A will forward it to the device assigned the IP address of 192.168.1.255.
