Solution
The Layer 2 attack that is mitigated by disabling Dynamic Trunking Protocol is a. VLAN hopping.
Here's a step-by-step explanation:
-
VLAN hopping is a network attack where an attacker can send packets to a network port that is not normally accessible from a given end system.
-
This is achieved by taking advantage of the automatic trunking protocol, like Dynamic Trunking Protocol (DTP), which is used to negotiate trunking on a link between two VLAN-aware switches.
-
DTP can be exploited by an attacker to make the switch port enter into trunking mode, which allows the attacker to access traffic across multiple VLANs.
-
By disabling DTP, you prevent the switch port from entering into trunking mode, thus mitigating the risk of VLAN hopping attacks.

Question 1Smith, a professional hacker, initiated a network sniffing attack on the switched Ethernet environment of a target organization. He employed an automated tool to flood the switch with a fake physical address until the switch translation table became full. When the switch entered fail-open mode, it started acting as a hub by broadcasting packets. Now, Smith could easily accomplish his goal of network sniffing.Identify the type of attack performed by Smith in the above scenario. 1 pointARP spoofing DHCP starvation MAC flooding DNS poisoning 2.Question 2Which of the following tool helps an attacker perform an ARP poisoning attack? 1 pointWireshark High Orbit Ion Cannon BetterCAP Nbtstat
