Which server platform on Windows supports multiple protocols including HTTP, HTTPS, FTP, FTPS, SMTP, and NNTP?

• A. Kestrel
• B. Apache
• C. Internet Information Services (IIS)
• D. Lighttpd

Answer: (C)

The key idea is recognizing Windows’ integrated server platform that can host a range of protocols in one stack. Internet Information Services (IIS) is Windows’ built-in server platform, designed to run web services and extendible with additional components. It handles HTTP and HTTPS for web content, and, through optional features, can support FTP/FTPS, SMTP, and NNTP as part of the same IIS ecosystem. This consolidation makes IIS the best fit for a Windows server that supports all those protocols. Kestrel is a lightweight HTTP/HTTPS server for ASP.NET Core and isn’t a full multi-protocol stack. Apache and Lighttpd are cross‑platform web servers; they can run on Windows but are not the native Windows server platform and don’t inherently provide the full set of protocols (like NNTP) as a single Windows-integrated solution.
