Network Security Scan is best described as:

Network Security Scan is best described as:

• A. A diagram showing system components and connections within a networked environment.
• B. The process by which systems are remotely checked for vulnerabilities using manual or automated tools.
• C. A technique to prevent sniffing.
• D. The method for time synchronization.

Answer: (B)

The main concept here is evaluating a network’s security posture by remotely checking systems for weaknesses using tools. A network security scan uses automated scanners (and sometimes manual checks) to identify vulnerabilities such as open ports, exposed services, missing patches, misconfigurations, and weak credentials. This helps map the attack surface and prioritize remediation, providing a snapshot of where defenses are strongest or weakest. It isn’t about drawing a diagram of components, it isn’t a technique to prevent eavesdropping, and it isn’t about time synchronization—those are separate concepts. So the description that fits best is the one describing the process of remotely checking systems for vulnerabilities with tools.
