Which of the following is a consequence of a DNS attack?

• A. Increased server load
• B. Diverted network traffic
• C. Enhanced service reliability
• D. Improved user experience

Answer: (B)

A DNS attack typically involves manipulating or compromising the Domain Name System, which is crucial for translating domain names into IP addresses. The correct answer, which is the diversion of network traffic, highlights a significant consequence of such attacks.

When a DNS attack occurs, attackers may redirect users trying to visit a legitimate website to a malicious site instead. This redirection can siphon sensitive information or lead users to harmful content, effectively diverting legitimate network traffic to unintended locations. This consequence can have serious implications for both users and organizations, potentially leading to data breaches or loss of critical information.

In contrast, increased server load can be a side effect of certain types of attacks, like DDoS attacks, but it is not a direct consequence of DNS manipulation. Enhanced service reliability and improved user experience are outcomes generally sought after in network management and application design, but they are not relevant outcomes of a DNS attack, as attacks typically compromise reliability and degrade user experiences. Such harmful activities focus on disruption rather than enhancement.
