Which of the following DDoS attacks overloads a service by sending inundate packets?

In the context of DDoS (Distributed Denial of Service) attacks, a network-centric attack is one that

targets the network layer of a system’s architecture. This type of attack aims to overload a service by

inundating it with a flood of packets, which can be achieved through methods like ICMP floods or

UDP floods. These attacks consume the bandwidth of the targeted site, effectively saturating it with

traffic and preventing legitimate traffic from being processed.
