Which of the following describes a common result of a DoS attack?

• A. Increased server speeds
• B. Network outage for legitimate users
• C. Improved detection of malicious traffic
• D. Enhanced user access privileges

Answer: (B)

A Distributed Denial of Service (DoS) attack typically aims to overwhelm a network, service, or server with an excessive amount of traffic, making it unavailable to legitimate users. This disruption can lead to a network outage, meaning that users trying to access the service may experience delays or an inability to connect altogether. The essence of a DoS attack is to render the resources inaccessible, thereby causing significant inconvenience and potential revenue loss for businesses and organizations relying on those services.

In contrast, the other options describe outcomes that do not align with the nature of a DoS attack. For example, increased server speeds would be counterproductive to the attack's objectives, while improved detection of malicious traffic or enhanced user access privileges would not likely occur as a direct result of a denial of service incident. Instead, those outcomes could relate to other security measures or incidents, but they do not characterize the primary result of a DoS attack.
