Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 654

Which type of DNS abuse exchanges data between two computers even when there is no direct connection?

Answer options

• A. malware installation
• B. network footprinting
• C. command-and-control communication
• D. data exfiltration

Correct answer: C

Explanation

The correct answer is C, as command-and-control communication involves a method where an attacker can send commands and receive data from compromised systems without needing a direct connection. The other options, such as malware installation and data exfiltration, do not specifically refer to the ongoing communication mechanism facilitated by DNS abuse.
