A. B. C. D.C
Frame flooding is a process in which a switch sends a broadcast frame out to all the ports on a VLAN to which the frame's destination MAC address is unknown. This process is also called unknown unicast flooding.
When a switch receives a frame, it looks up the destination MAC address in its MAC address table. If the MAC address is not found, the switch sends the frame to all the ports on the VLAN, except for the port on which it was received. This is done to ensure that the frame reaches its intended destination.
Answer A is incorrect because frames are not sent to ports assigned to other VLANs during frame flooding. Answer B is partially correct because frames are sent to ports that have a matching entry in the MAC address table, but this doesn't necessarily mean that all ports will receive the frame. Answer C is the correct answer because frames are sent to every port on the switch in the same VLAN, except from the originating port. Answer D is incorrect because it doesn't take into account the fact that frames are not sent to the originating port.
Frame flooding can cause a few issues in a network. First, it can cause unnecessary traffic on the network, which can lead to congestion and poor performance. Second, it can create security vulnerabilities because frames are sent to all ports, including those that may not be authorized to receive them. Finally, it can cause MAC address table instability because the table is constantly being updated with new MAC addresses.
