What attack floods networks with broadcast traffic so that the network is congested?

A.
Spoofing

B.
Teardrop

C.
Brute force

D.
SMURF

Explanation:
SMURF attack — This attack floods networks with broadcast traffic so that the network is congested.
The perpetrator sends a large number of spoofed ICMP (Internet Control Message Protocol) echo
requests to broadcast addresses hoping packets will be sent to the spoofed addresses. You need to
understand the OSI model and how protocols are transferred between layer 3 and layer 2 to
understand this attack. The layer 2 will respond to the ICMP echo request with an ICMP echo reply
each time, multiplying the traffic by the number of hosts involved. Engineers should turn off
broadcast capability (if possible in your environment) to deter this kind of attack.
