A malicious user floods a switch with frames hoping to redirect traffic to the user’s server. Which of the
following attacks is the user MOST likely using?

A.
DNS poisoning

B.
ARP poisoning

C.
Reflection

D.
SYN attack

Explanation:
Address Resolution Protocol poisoning (ARP poisoning) is a form of attack in which an attacker changes the
Media Access Control (MAC) address and attacks an Ethernet LAN by changing the target computer’s ARP
cache with a forged ARP request and reply packets. This modifies the layer -Ethernet MAC address into the
hacker’s known MAC address to monitor it. Because the ARP replies are forged, the target computer
unintentionally sends the frames to the hacker’s computer first instead of sending it to the original destination.
As a result, both the user’s data and privacy are compromised.
