In the attack, which doesn’t use ICMP in the following? (Select two answers).

A SYN flood.

A SYN flood is a type of denial-of-service (DoS) attack that exploits the three-way handshake used to establish a TCP connection. The attacker sends a large number of SYN (synchronize) packets to the victim server but does not respond to the SYN-ACK (synchronize-acknowledgement) packets that the server sends back. This causes the server to allocate resources for each half-open connection, which can eventually exhaust the server's resources and make it unavailable to legitimate users.
A peer-to-peer attack is a type of DoS attack in which the attacker uses a large number of compromised hosts to send traffic to the victim server. The attacker can control these compromised hosts using malware or botnets. Peer-to-peer attacks can be used to launch a variety of DoS attacks, including SYN floods.
