What is the default port number for Syslog?

514 (UDP)
8080
21
22

The correct answer is: 514 (UDP)

The default port number for Syslog is 514, which primarily uses the User Datagram Protocol (UDP). Syslog is a standard protocol used for message logging in network devices and servers. It facilitates the transmission of event messages from various sources to a centralized logging system. The choice of UDP for this protocol allows for low overhead and efficient transmission of the log messages, making it ideal for real-time logging, even though it does not guarantee delivery. The other options do not relate to Syslog: port 8080 is commonly used for web traffic; port 21 is associated with FTP (File Transfer Protocol); and port 22 is used for secure shell (SSH) access. None of these protocols provide the logging functionality that Syslog does. Therefore, the association of port 514 with Syslog is well-established and widely recognized in network and systems administration contexts.
