A denial of service (DoS) attack is characterized by overwhelming a system, service, or network with excessive traffic or requests, making it impossible for legitimate users to access the targeted resource. In this scenario, a server being overloaded with traffic represents a classic example of a DoS attack. In such cases, the server is inundated with requests that exceed its capacity to respond, thereby denying service to legitimate users. The goal of this attack is typically to disrupt the availability of a service, demonstrating a clear intention to impair access through resource exhaustion. The other scenarios do not fit the definition of a denial of service attack as closely. A computer running out of storage space relates to resource management issues rather than an intentional attack. An application being hacked and shut down might represent different malicious activities, likely involving exploitation or taking control rather than a pure denial of service. A user forgetting their password is a common user error and does not pertain to malicious activity or an attack on system availability. Thus, the scenario of a server being overloaded with traffic stands out as the best illustration of a denial of service attack.
