What is the result of a cyber attack that floods a server with requests?

A cyber attack that floods a server with requests is typically referred to as a Distributed Denial of Service (DDoS) attack. The primary outcome of such an attack is that it overwhelms the server's capacity to handle requests, ultimately leading to a situation where legitimate users can no longer access the services provided by that server. As the server is inundated with excessive requests, it struggles to respond to each one, which results in degraded performance or outright unavailability. Therefore, the correct result of this scenario is that the server becomes unusable for its intended purpose.

The other choices do not accurately reflect the consequences of a request flood. Increased data storage, improved security measures, and faster data processing are not outcomes associated with a server being overwhelmed by malicious traffic. Instead, these options imply better performance capabilities of a server, which contradicts the impact of a DDoS attack.
