What can be a consequence of a DDoS attack?

• A. Increased system performance
• B. Interrupted online services for users
• C. Improvement in software security
• D. Enhancement of network bandwidth

Answer: (B)

A DDoS (Distributed Denial of Service) attack is designed to overwhelm a target—in this case, an online service—by flooding it with a massive amount of traffic. As a result, this can lead to significant disruptions, rendering the service unavailable to legitimate users. The focus of a DDoS attack is to create an interruption in services, which often results in users being unable to access websites, applications, or any online platform during the attack. This directly correlates with the consequence identified in the answer, as users experience interrupted services when the system is unable to handle the excessive load prompted by the attack.

On the other hand, increasing system performance or improving software security are not associated with the aftermath of a DDoS attack. Rather, a DDoS attack typically highlights vulnerabilities within a system or network rather than enhancing them. Similarly, enhancement of network bandwidth does not occur as a direct consequence of such attacks; instead, bandwidth is consumed excessively, which leads to a degradation of service for users. Therefore, the consequence of interrupted online services is the most accurate representation of what occurs during a DDoS attack.
