Question 34

These actions will most effectively prevent known exploits.

By keeping the switches updated with the latest operating system, ensuring servers have the latest patches, and maintaining current endpoint definitions, the engineer effectively reduces the risk posed by known vulnerabilities that hackers may exploit.

A) Zero-day attacks

Zero-day attacks leverage vulnerabilities that are not yet known to the software vendor, making them difficult to defend against, even with updated systems. Therefore, while updates can help mitigate risks, they do not specifically prevent zero-day attacks.

B) Insider threats

Insider threats originate from individuals within the organization who may misuse their access. Updating software and systems does not address the human factor involved in insider threats, which are influenced by employee behavior rather than technical vulnerabilities.

C) End-of-life support

End-of-life support refers to software that no longer receives updates or patches. The actions described do not directly prevent end-of-life support issues; instead, they focus on maintaining current systems rather than managing outdated ones.

D) Known exploits

By ensuring that systems are updated with the latest OS, patches, and definitions, the engineer effectively protects against known exploits. These updates typically include fixes for vulnerabilities that have been publicly identified and documented, thereby closing the door on potential attacks that exploit these weaknesses.

Conclusion

The actions taken by the engineer are specifically aimed at mitigating risks associated with known exploits by addressing vulnerabilities. In contrast, options A, B, and C are either unrelated or insufficient in tackling the threats posed by vulnerabilities that are already known and documented. Thus, option D is the most appropriate choice based on the context provided.
