NO.1 Which description correctly describes a MAC address flooding attack?
A. The attacking device crafts ARP replies intended for valid hosts. The MAC address of the attacking
device then becomes the destination address found in the Layer 2 frames sent by the valid network
device.
B. The attacking device crafts ARP replies intended for valid hosts. The MAC address of the attacking
device then becomes the source address found in the Layer 2 frames sent by the valid network device.
C. The attacking device spoofs a destination MAC address of a valid host currently in the CAM table. The
switch then forwards frames destined for the valid host to the attacking device.
D. The attacking device spoofs a source MAC address of a valid host currently in the CAM table.
The switch then forwards frames destined for the valid host to the attacking device.
E. Frames with unique, invalid destination MAC addresses flood the switch and exhaust CAM table space.
The result is that new entries cannot be inserted because of the exhausted CAM table space, and traffic is
subsequently flooded out all ports.
F. Frames with unique, invalid source MAC addresses flood the switch and exhaust CAM table space.
The result is that new entries cannot be inserted because of the exhausted CAM table space, and traffic is
subsequently flooded out all ports.
Answer: F
