Refer to the exhibit.
What is occurring in this network?
A . ARP cache poisoning
B . DNS cache poisoning
C . MAC address table overflow
D . MAC flooding attack
Answer: D
Explanation:
The exhibit shows a network diagram with a switch, a router, and two hosts. The switch has a MAC address table that maps the MAC addresses of the connected devices to the corresponding ports. A MAC flooding attack is a type of attack that aims to overload the switch’s MAC address table by sending a large number of frames with spoofed source MAC addresses. This causes the switch to enter a fail-open mode, where it broadcasts all incoming frames to all ports, effectively turning it into a hub. This allows the attacker to sniff the traffic between the hosts and the router, or launch other attacks such as ARP spoofing or man-in-the-middle
