What are botnets used for?

• A. To manage a cluster of servers.
• B. To monitor traffic in real time.
• C. To create and send spam or viruses.
• D. To back up data securely.

Answer: (C)

Botnets are networks of computers that have been compromised by malware and are controlled by a single attacker. This setup lets the attacker coordinate actions across many machines, amplifying impact and making it harder to stop. The typical malicious uses include creating and sending large volumes of spam and distributing viruses, because leveraging thousands of machines increases reach and effectiveness. The other described tasks—managing a legitimate server cluster, monitoring traffic with defensive tools, or backing up data securely—are not what botnets are used for. So the best fit is the description of spam and malware distribution.
