During port scanning, what type of information is commonly identified?

• A. Addressing, Routing, Version Numbers, Patch Levels, Protocols/Services Running
• B. Usernames And Passwords
• C. Physical Environment
• D. Weather Data

Answer: (A)

Port scanning maps a target's reachable surface by probing ports to see what is open and what services respond. The information commonly identified includes how the host is addressed and reachable through the network (addressing and routing), the software running on the host (version numbers and patch levels), and the protocols or services listening on each open port. This combination helps gauge what could be exploitable and what defenses are needed.

Other options don’t fit because port scanning doesn’t reveal usernames or passwords, which require authentication breaches or credential harvesting; it doesn’t provide data about the physical environment; and it doesn’t give weather information.
