Ref: Flooding vs Broadcast - Cisco Community
Post by Kristian Alexander Brown
“…
Flooding is sometimes known as an unknown unicast. This happens when a switch receives a frame with a destination mac address it does not have in the CAM table. It will flood it out all ports except the receiving port of the frame.
…”
A. Frames are sent to all ports, including those that are assigned to other VLANs.
Wrong answer.
B. Frames are sent to every port on the switch that has a matching entry in MAC address table.
Wrong answer.
C. Frames are sent to every port on the switch in the same VLAN except from the originating port.
Correct answer.
D. Frames are sent to every port on the switch in the same VLAN.
Wrong answer.
During the process of frame flooding, frames are replicated and forwarded to all ports on a network switch, except the port from which the frame was received. This technique is commonly used in Ethernet networks when the destination MAC address of a frame is unknown or if the frame needs to be broadcasted to multiple devices on the network.
Therefore answer is C.
No C is correct, you provided IPV^ multicast addresses which operate at layer 3 and are known as packets. The question states layer 2 frames meaning mac addresses.
