A DNS amplification attack involves the exploitation of the domain resolution service's infrastructure to turn small queries into much larger packets, overwhelming the victim's network with a high volume of traffic, aiming to exhaust bandwidth and resources which fits the scenario described. In contrast, ARP spoofing refers to the forging of ARP messages to link an attacker's MAC address with the IP address of a legitimate computer or server within a network, a tactic that does not directly affect domain resolution infrastructure traffic volume. A SYN flood is an attack using the TCP protocol handshake process to consume resources, however, it does not specifically target domain resolution infrastructure. A jamming attack is a disruption of wireless networks by flooding them with signals to disrupt communications, which is unrelated to the increase in traffic to a domain resolution system.
