A MAC address flood attack is occurring on the LAN. During this attack， numerous frames areforwarded to a switch which causes the CAM table to fill to capacity. How does this action benefitthe attacker？（）
A
All traffic is tagged with a specific VLAN ID from the VLAN of the attacker and is now viewable
B
Clients will forward packets to the attacking device， which will in turn send them to the desireddestination but not before recording the traffic patterns
C
All traffic is redirected to the VLAN that the attacker used to flood the CAM table
D
All traffic is flooded out all ports and an attacker is able to capture all data
E
None of the other alternatives apply

After connecting a PC to an available port on a switch, you find that the PC can not access any of the resources on the LAN. No other PC's connected to the switch appear to be having any issues. What is the most likely cause for this problem?A．The router lacks a routing table entry for the new hostB．The host switch port is assigned to the incorrect VLANC．The host MAC address is incorrectly configuredD．A STP instance for the new host has not been initializedE．The switch does not have the MAC address hard coded in the CAM table.

You suspect that a hacker may be performing a MAC address flooding attack somewhere within the network. Which description correctly describes a MAC address flooding attack？（）A、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.B、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.C、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.D、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.E、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.F、Frames with unique， invalid source MAC addresses flood the switch and exhaust CAM table space.
