What does a service banner typically reveal?

• A. The service name and version
• B. The vendor password
• C. The host's OS
• D. The user accounts

Answer: (A)

A service banner is the initial text a server sends when you connect, and it usually identifies the software running and its version. This quick fingerprint helps security testers determine exactly what service is exposed and which version is in use, so they can check for known vulnerabilities and apply the appropriate patches. For example, an HTTP banner might reveal “Server: Apache/2.4.46” or an FTP banner might show a specific FTP server version. The options about a vendor password, the host’s operating system, or user accounts aren’t typically disclosed by a banner, so they aren’t what the banner is intended to reveal. If needed, banners can be restricted or customized to avoid leaking version details.
