What type of attack involves sending spoofed DNS requests to create larger responses to another target?

A reflected DDoS attack involves sending forged DNS queries to DNS servers with the source address spoofed to that of the intended target. When the DNS server responds, it sends the data to the victim, amplifying traffic directed at that target, which can overwhelm their network resources and lead to a denial of service.

In the context of this attack, the use of DNS query responses allows the attacker to leverage the DNS infrastructure to create a significant volume of traffic without having a direct connection to the target. This technique effectively amplifies the attack, making it much more impactful. The attacker aims to create a situation where the legitimate traffic size is substantially increased, resulting in a denial of service for the targeted system.

The other options represent different types of attacks unrelated to the mechanism of using spoofed requests to solicit larger responses. Each has its distinct characteristics and methods of operation, making them unsuitable in this context.
