What kind of information can a Network Scan retrieve?

The ability of a Network Scan to retrieve details about devices on the network is integral to understanding the infrastructure and topology of that network. A Network Scan typically identifies and gathers information such as device types, IP addresses, MAC addresses, operating systems, and any services or applications that are currently running on those devices. This type of information is crucial for network management and security assessments, as it provides a clear inventory of what devices are present, which can help in monitoring, troubleshooting, and optimizing network performance.

The other options provided, while relevant in different contexts, do not align with the primary function of a Network Scan. Installation dates of software and configuration settings of network switches, for example, may require more targeted scans or specific protocols, and real-time performance metrics typically involve monitoring tools rather than just an initial scan. Thus, B stands out as the most accurate reflection of the capabilities of a Network Scan.
