Which three options are types of Layer 2 network attack? (Choose three)
The correct answers are A, B, and E. Spoofing attacks, VLAN hopping, and ARP attacks are all types of Layer 2 network attacks.
A. Spoofing attacks: In a spoofing attack, the attacker impersonates another device on the network by using a false source address in a data packet. This can be used to intercept sensitive information, such as passwords or credit card numbers.
B. VLAN hopping: VLAN hopping is a technique where an attacker gains unauthorized access to a VLAN (Virtual Local Area Network) by exploiting a vulnerability in a network switch. This can allow the attacker to access sensitive information on the VLAN.
C. Botnet attacks: Botnets are networks of compromised computers that can be used to carry out attacks, such as Distributed Denial of Service (DDoS) attacks, which overwhelm a target system with traffic. However, botnet attacks are not typically considered to be Layer 2 attacks.
D. DDoS attacks: Distributed Denial of Service (DDoS) attacks are carried out by flooding a target system with traffic from multiple sources. However, DDoS attacks are not typically considered to be Layer 2 attacks.
E. ARP attacks: In an ARP (Address Resolution Protocol) attack, the attacker sends falsified ARP messages to associate their own MAC address with the IP address of another device on the network. This can allow the attacker to intercept traffic intended for the targeted device.
F. Brute force attacks: Brute force attacks are typically used to crack passwords by repeatedly trying different combinations of characters until the correct password is found. However, brute force attacks are not typically considered to be Layer 2 attacks.
