In Nmap, which option is used to retrieve service banners?

• A. Hostnames
• B. Service banners
• C. OS detection
• D. IP addresses

Answer: (B)

Understanding how Nmap grabs banners from services is what this is about. A service banner is the text a service sends when you connect to its port, often including the service name and version. Nmap collects these banners as part of its version detection process, which is what enables you to see banner information. The capability you’re asked about is simply the service banners feature, which is specifically about retrieving those banners. Other options like OS detection, hostnames, or IP addresses serve different purposes and don’t fetch banners.
