What does network reconnaissance involve?

• A. Gathering intelligence on enemy troops
• B. Exploring a network to identify devices and vulnerabilities
• C. Mapping physical locations of network cables
• D. Establishing communication with allied forces

Answer: (B)

Network reconnaissance is the process of gathering information about a target network to understand its structure, assets, and potential weaknesses. It involves discovering what devices are on the network, what services they run, IP addresses and topologies, open ports, operating systems, and configurations. This creates a map of the network’s attack surface and helps identify vulnerabilities that could be exploited or mitigated. The option describing exploring a network to identify devices and vulnerabilities matches this idea precisely, since it covers both asset discovery and weakness assessment essential to reconnaissance. Other choices describe tasks outside digital network exploration: gathering intelligence on enemy troops refers to terrestrial military targets, mapping physical network cables focuses on physical infrastructure rather than digital assets, and establishing communication with allied forces is about coordination rather than surveying a network.
