Port 9090 is associated with which application?

Openfire
HSQL
Tor
Yersinia

The correct answer is: Openfire

Port 9090 is commonly associated with Openfire, an open-source real-time collaboration server based on the XMPP (Extensible Messaging and Presence Protocol) protocol. Openfire provides functionalities for instant messaging, presence information, and group chat. The default configuration typically uses port 9090 for its web administration console, allowing administrators to manage the Openfire server settings and monitor activity through a web interface. The other options do not primarily associate with port 9090. HSQL, for instance, commonly utilizes ports like 9001 for database services. Tor is primarily known for using port 9050 (for its SOCKS proxy) and 9051 (for its control port), whereas Yersinia, a network attack tool, does not have a default association with any specific port like 9090 either. Thus, understanding the primary function and defaults of Openfire helps clarify why it is the correct choice.
