Which protocol distributes, inquires into, retrieves, and posts news articles among the ARPA-Internet community?

• A. Usenet newsgroup
• B. Google Alerts
• C. Sherlock
• D. Network News Transfer Protocol (NNTP)

Answer: (D)

Network News Transfer Protocol is the mechanism that moves Usenet content between servers. It’s designed for distributing, inquiring into, retrieving, and posting news articles across the ARPA Internet community. Usenet consists of many newsgroups, and NNTP provides the standard set of commands that clients use to list groups, read headers, fetch articles, and post new ones, with servers exchanging articles to keep groups synchronized. This protocol is what makes cross-server article propagation possible, rather than the service itself or a search/alert tool. For context, Usenet newsgroups are the topics or discussions, Google Alerts is a newer web-monitoring service, and Sherlock is an old Mac search tool; none of those handle the actual transfer of Usenet articles between servers.
